This was a great place to stay. My partner and I spent three nights here and it was a lovely spacious flat for two, and would be comfortable enough for four.
We chose the flat as it was close to the Olympia Theatre as we were going to a gig there. Flat is about 10mins walk to the main inner areas of Dublin (Trinity college etc), opposite Christchurch cathedral and has many pubs, restaurants and shops directly below it. The flat itself has all the amenities you'd want and handily also has a taxi rank outside.
Communication with Marco was great and check-in was easy. I'd recommend this and rebook if we go back to Dublin.
