My family stayed in Simone's apartment during visiting me in Lisbon.
The place is really lovely with spirit of an old Lisbon's house and it's situated on perfect start point for visiting the city (walking distance to Martim Moniz square, bus station just across the street, also supermarket is really close).
I also have to mention that the place is very good equipped (they had there everything they needed) and it was very clean and in perfect condition. What they also appreciate was air conditioning, as their visit was during a really hot August weekend.

If any or my friends are coming to visit Lisbon, I definitely arrange this place for them :)
