The apartment itself was lovely - beautiful view onto the square, very spacious and great central AC. However, almost everything else was not up to scratch.
The biggest problem was that we had no hot water and only one working toilet for the entire stay - while AirBNB refunded us for a portion of our stay, when we asked Jason for a resolution he stopped responding to our messages. The hot water was also obviously a pre-existing condition as Jason mentioned a few hours after we checked in that someone was coming to check the broken boiler (before we realised there was no hot water)
The host also left dirty washing hanging in the apartment so when we arrived it was hanging out - which made the apartment feel like it hadn't been cleaned. The shower was also not clean in the master bedroom.
The check in process was also bizarre and we had organised to meet the host outside the apartment at 3:15 - he didn't show up and we were let in by the (very confused) cleaners. He eventually showed up at 4:30 so I'm glad that the cleaners were there so we weren't waiting around for an hour!
The host also let people come to fix a broken window into the apartment early one morning without notifying us (so we had no idea who they were/what they were coming for).
In saying this, the apartment has huge potential - it was very nicely laid out and had a good sound system which was great. It was also really spacious. However, I wouldn't book this as a serviced apartment as it lacked most of the services we paid for.
