PROS
1. Fantastic location
2. Cleverly designed micro-apartment with everything a couple would need for a short stay (assuming only eating in for breakfast)
3. Super-clean.
4. Pablo, who looks after the apartment, is a real star and met us/helped us with our bags.
5. Coco, the host, allowed us a late check-out (1600) for no extra charge, which was much appreciated as we had a late flight.

CONS
1. The second bedroom is only a study which can be converted into two single beds. These beds are narrow, small & hard and once made up there is next to no room left for two adults to walk about etc. Just about OK for kids or a baby. Think sleeping compartment on a train!
2. This isn't a place to spend a lot of time, as it's quite dark and, while perfectly comfortable, we found the living room a bit dated and not quite what we were expecting from the description/pictures. But fine for short downtime between seeing the sights. Also kitchen very clever but tiny, so we never even tried to cook. But as you within walking distance of so many amazing places to eat, there's no need.
3. It can be noisy. The internal walls are thin and you can hear others using the bathroom etc. More irritatingly, from very early in the morning, you are woken up by noises from within the building and outside. Just have to be up and about early!
4. Bring your own information/tips and do your own research about where to buy stuff/go locally. There isn't much info in the apartment and what there is is sparse and more about 'the rules' and fines you will have to pay if something gets damaged! We asked where to buy basic food etc when we arrived and they were unable to tell us.
5. Few minor quibbles: strong smell of damp in the hallway and the loos do not flush properly.
6. Communications not always straightforward and we had a few quite stressful moments as a result.
