The stay is well centered in the middle of Lisbon and is within the reach of lots of good things. Bairo Alto is the party district so be aware that it is full of bars and people enjoying themselves. So depending on what you are looking for, this apartment is either awesome situated or pretty terrible.
The apartment itself is functional, with 3 rented rooms with a small shared bath and a small shared kitchen. It is easy to make friends with the other roommates and go out with them.
Andre itself is quite uncomplicated and fast to respond to issues.
