Nice flat, enough space for 4, however being 5 we've managed well. The flat has everything you could possible need for your stay. Frank was a lovely and friendly host, check in/out was quick and easy, same with the communication, he was really responsive.
The flat is located in a safe area (just the street entrance is a bit dark) but we felt safe all the time. It's situated in the north part of Dublin, which is really nice, and walking distance to the temple area o main touristic attractions. Definitely recommended
