I cannot recommend this place enough. The location is unbeatable, very quiet yet so central that we were able to explore Dublin entirely on foot. If you don't want to walk far, the direct neighborhood offers a very attractive and lively pub and bar scene.
The apartment is stylish and spacious, ideal for our party of four. It even includes a membership card for the pool and fitness area of the building and a parking space for a car (which we didn't use).
Check-in / check-out was super fast and easy via the security guard in the building, the host (Elaine) is very friendly and responsive.
