I had a wonderful stay at Jose and Vadym's flat. They were both gracious and welcoming hosts. The flat was clean and very comfortable. They have thought of everything you may have forgotten to pack and have it available for you. It was also very nice to have use of a private bathroom.
Although the flat is slightly outside the city centre, it was very accessible by public transport or you can have walk into town in about 20 minutes.
I would highly recommend staying with Jose and Vadym if you are ever in Dublin. I hope I can stay with them again the next time I visit the city.
