The apartment is just perfect! It's located in a very center place of Lisbon, close to a lot of supermarkets and had all the amenities that we need for our stay.
Ricardo is very nice, showed us the place (it has two heaters that saved our nights!) and also gave us an advice for a place we could park our car at a close parking lot.
The only thing that we didn't like was the fact that it didn't have a elevator (but that's the price for staying in a center apartment!).
We absolute loved it! Thanks Ricardo! :)
