Great central location - the brazen head is around the corner and a 10-min walk to temple bar. Very clean overall, with comfortable beds.
Not many negatives, but just to note that the shower pressure is quite weak. (Also, just to repeat what others have said that it does mention on the listing that there is no WiFi, so just to bear this in mind when booking!)
Overall, we had a great time and Maire is a fantastic host - very communicative before check in and extremely accomodating, allowing us a slightly earlier check in time and letting us leave our bags at the apartment after check out so we didn't have to keep them with us throughout the day (before our flight later on).
