Everything was good, the acces very clear with the instructions and the check-in system.
Our main issue were that the kitchen tap water drained huge water amount to a bucket under it, so it got impossible to continue using it when the bucket was getting full, with the linked smell it produced when opening the door under it.
Guess it will be fixed soon, so definitely a nice place to stay, good location at st. Antoni's market and easy to move by metro to other places.
