It is a nice and clean place, it is in the center so everything is really close, the apartament is very little , it is not exactly as the pictures, and the 2 rooms are not really separated wich is a good thing if you travel with your kids, and it is a bad thing if you travel with someone else and you want privacy.
The bad thing is that you must go to take the key from a different address, wich can be difficult if you have big luggage. It is good for a few days, like a citybreak and the advantage is that is in Alfama :)
Enjoy!
