Unfortunately I would not recommend the apartment because:
-The bathroom door wasn't closing, it was always open, very uncomfortable since we could not use it. We asked for a change in the apartment but they didn't do so, however they have us a monetary compensation.
-There was a horrible smell in the apartment and we could not ventilate it good enough since there is no windows and the door is the only separation between the apartment and the street (take it also in account for your own safety).
- In order to get the keys you need to go to a Welcome center which is 25 minutes away from the apartment (remember it is Lisbon, it's 25 minutes up a slope, so if you choose this apartment and you have suitcases take either public transport or a taxi).
Good thing of this appartment they're quite fast answering messages but almost everytime it would be a new person I was talking to.
Enjoy Lisbon, very beautiful city!
