Caolan's place is located in a very convenient position, you can practically reach every location in center Dublin within 20 minutes walk. Caolan was available for every question we had but also very discreet. The room doesn't lock, and there is no key for it so it remains open all the time. There's a disco right outside the room's window and the music is very loud until late in the night (during the weekend). The room and the bathroom were not very clean. In conclusion, given all the circumstances and the great position we recommend this apartment.
