Ireland has always been famous for its Céad Míle Fáilte, and this weekend many tourists pouring in will be finding out exactly what it is all about.

For many international communities living here that warmth is also felt, with the country consistently ranking as one of the friendliest in the world.

Many people move to Ireland to study and work, with English-language education being one big draw, while the tech sector is also an area that is attracting a lot of people from overseas.

So what is life like for these communities? And how welcome do they feel here?

On Thursday night, David Keeler and Karina Vassiljeva held their Strictly Salsa class at Dublin’s National Stadium on the South Circular Road.

They usually run in its main arena, but on this particular night it was booked for another event (which we'll get to later).

Because of this they were in a smaller room, and despite 80to 90 people coming in, David Keeler said that is "probably quiet" compared to other weeks.

He said that at least 15 to 20 nations are represented on this one floor.

Flying the flag for Bulgaria was Milena, who moved to Ireland 12 years ago.

"I’ve had a very good experience across several jobs [in Ireland]. Some of my best friends have been Irish through the years," she told RTÉ's This Week.

"Especially the social life. They meet after work, they go out for drinks. I have been in other countries, for example a couple of years in Denmark, and it was very very different.

"At 4.30/5pm everybody just went home."

Then there’s Fabio, a dual Portuguese-Venezuelan national.

"The Irish people are very open and also making fun.

"I was living in Portugal before coming here. So I moved from Venezuela to Portugal, and then here. And if I compare, the Irish people are more open than the Portuguese. Way more."

As St Patrick’s Day approaches there has been many celebrations worldwide, particularly in Australia where Irish acts have been attracting huge crowds.

Here at home there are people doing similar work for their diasporas.

One of those is Ayush Mann from India, who helped bring 700 people together to celebrate the Hindu festival Holi at St Laurence O’Toole’s centre off Sheriff Street on Saturday morning.

It was a colourful affair, literally, as people threw paint and danced to some Bollywood hits.

"People are very supportive [here]. They welcome different nationalities, that’s the best thing about Ireland," Ayush Mann said.

Those attending had a lot of positive things to say about their experience here.

"Guinness, we love Guinness, and Baby Guinness," one man says laughing.

"I have lived in the UK and other countries, but making a friend here is much easier than anywhere else."

Another woman, Vino said she found older people "especially warm", saying she often felt like they were treating her like a granddaughter.

However, when asked if she had many Irish friends she said it was hard to make "close ones".

"But when we are in the classroom they don’t leave you behind when they go out for lunch or anything. They [her Irish classmates} care about you and take you with them."

The night before Holi celebrations another community had taken over Dublin’s Sugar Club on Leeson Street.

Roy Ayers, Charles Bradley, and Erykah Badu are just some big names that have stood on that stage, and now Kemal Ayça can add himself to that list.

The Turkish comedian performed in his native tongue in front of around 100 people.

The night was organised by Bizz events, which is run by husband-and-wife duo Ersin and Ebru Genel.

Ms Genel said: "I’m living in Dublin around six years. My kids are safe here and they love it here.

She said they started Bizz because they wanted to bring the Turkish community together, and also to promote more female entrepreneurship.

Although the performance was in Turkish, a lot of their events revolve around theatre while their music sessions have attracted Irish audiences.

Ms Genel said there is a strong crossover between Turkish and Irish acoustic guitarists who are taking an interest in each other’s styles.

Many people at Mr Ayça’s show said that other than language, they don’t notice a major difference between themselves and Irish people.

One man, Selim, said: "I kind of find Irish people like Turkish people when it comes to having conversations with foreigners.

"When you walk on the street, when they see something that they are interested in, I’m taking photos for example, they see with my camera, or with my son, or my family, they always start a conversation.

"This is kind of like in Turkey."

On Thursday, as Strictly Salsa’s classes were under way, around 1,400 Brazilians lined up to get into the National Stadium’s main arena.

Pagode band Sorriso Maroto had flown in to play, and it was a big deal.

Although not a household name in Ireland, it would be fair to say they are very big back home and they are currently selling shows out across Europe.

This show was put on by the events company Green Group, who are focused on the Brazilian community.

"Ireland is amazing, people are friendly," one fan said.

"I like the weather because in Brazil it’s very warm. It’s nice to feel a little cold breeze. I love people here, they are always nice to us."

Another man, Oliff, said he feels very connected to people here, although Irish friend groups can be a "little bit hard" to crack as "they grew up together so are a little bit bound".

"But I lived with an Irish family, and they showed me the Irish culture and now I feel like they are my family too."
