The apartment is perfect for a group with 4 large bedrooms (real comfortable beds), despite the fact there is only one bathroom. Romana was really helpful, allowing us to check in early and check out 2 hours later as there were no reservation after us. There are 4 sets of keys, so very practical to be independent even in a large group.
3 bedrooms out of 4 overlooks the air rail, but it did not disturb us, but it can if you have a light sleep.
The building is bit weird, and you have to lock all the entrance doors (3) with a key, which is dangerous in case of fire.

Overall we had a very pleasant stay.
