Fabio was a welcoming, friendly host who's communication was fast and accurate. He answered all questions I had prior to arrival.
The flat itself was just as described- clean, tidy, stylish and in a perfect location right on the Ascensor da Bica line. This makes it great for orienting yourself in the city and puts you right next to one of the best spots for photos of the narrow tram systems. The tram starts running from 7am though and comes right past the flat door, so be mindful of the noise as it clatters by - by the second day we had gotten used to it. The street is also very steep and not obvious at first if you approach from the main road by the ascensor entrance. Again, no problem for us but might make it tricky for travellers with large luggage.
There are lots of great bars and restaurants that are easily walkable, including the Timeout Market. The two metro stops close by made it simple and fast to get to from the airport.
I would highly recommend Fabio's flat for a short break in the city - great location and a great host.
