Mary and Peter are a lovely couple. We stayed in for three days and had a wonderful experience. Their house is very cozy and you can reach the city centre easily, because the bus stop is just few minutes from the house. Also the neighbour is very well served, you can find here whatever you need (supermarkets, super cute pubs, ecc). If you're staying at Mary and Peter's you will probably have interesting conversations with other guests of the house, since Mary and Peter are two very open minded people that welcome in their house travellers from all over the world. Last but not least, if it's your first time in Dublin don't worry because Mary and Peter will advise you on the best things to do here! Definitely worth it!
