The flat was very cosy and in a good position. We were 3 but also in 4 it will be still alright.
The area is safe and the people are friendly. If you wanna stay local there are lots of restaurants and pubs a couple of minutes walking from the flat.
There are also buses and a tram station 5 minutes walking far that takes you to St. Stephen Green in about 10 minutes. Anyway the flat is about 25 minutes walking from the centre.
I would be happy to go back there.
