I really recommend The Rest for your stay in Galway. The location is the best : in the city center, close to the sea and with a lot of facilities around (the market on Saturdays, an amazing cheese and wine shop in the street behind, a French bakery with the best croissants and pastries).
The apartment is big, clean and there are all the equipments you need for a short or long stay. The decoration makes the place very cosy and we can even feel "at home" sometimes.
The communication with the owners was also perfect and they were always efficient and quick to reply.
So thank you for this really nice experience !
