The place is really lovely, clean and well furnished. We stayed there with three friends and the place was perfect. There is a big fridge, and everything needed to cook (and a dishwasher to clean after that ;-)). The place is not so far from city center (25 min walking to Temple Bar) but with the unstable weather, we also used public transportation.
We haven't got the chance to meet with Joan but we had all information to check in the apartment. There was also some information on all tourist activities around in the apartment.
