Pros: the host is lovely, and was really helpful getting us a taxi and with the laundry. The location is amazing. So close to the main tourist area, loads of cafes and shops nearby.
Cons: there are no windows which gets a bit clautrophobic. There are lots of people in the building and as the walls are very thin so you can hear everything.
But ultimately this is all reflected in the cost and the main attraction of this place is the location.
