We stayed at Gustavo's place for three nights and it was just perfect. The rooms are very spacious and the bed was comfortable. Communication with Gustavo was excellent, we even arrived a little early and he was already there waiting for us to give us the keys and show us the apartment. The area is lovely too, close to the centre, but also nice and quiet if you want to relax. The private parking space is gold if you're in Lisbon with a car, since parking can be a bit of a nightmare. All in all we really enjoyed our stay there and would definitely recommend it to anyone thinking of staying in Lisbon!
