Awesome host and place to stay! Me and my wife stayed for 2 nights in August there, and it was really good place for us - in the center of the city, close to all places of interest and transport ( which turned out quite easy to use and not so expensive as in London:). The main USP of the flat is the view from the roof terrace , we usually have a diner right there, on the "Lisbon roof" :).
Tiago is amazing host - he so quickly replied on all our requests , provide all requested info and support (he recommended us really cool surfing school).
Highly recommended place :)
