The flat was great for our ~2 week stay. Its in a great location, close to some great brunch spots and Monumental metro station.
As someone has mentioned in another review, it is managed by a company so doesn't have that homely feel but it wasn't a problem for us. It was a little rough around the edges due to wear and some of the cushion covers were dirty but I've fed this back to them so hopefully they will sort that out.
The communication from the Host was excellent, we were in Barcelona for a festival and i'd heard of people getting their accommodation cancelled at the last minute but I didn't feel like that was going to happen here as they were communicating with me from a few days prior.
The apartment was a great size for 2 but I think if you had more adults it would be a bit of a squeeze as the bathroom is accessed via the main bedroom.
