Our stay at Felipe's flat was just perfect.
Felipe was really quick to answer and even provided us with some useful info on the surrounding of the apartment (restaurants, shops, bus, metro...). He was there when we arrived for the check-in and gave us plenty of advices for our stay. He then remained quickly reachable during our whole stay if we ever needed something.
The apartment itself is very well located: 1 minute from restaurants, 5 minutes form supermarket, 3-5 minutes from metro, and every nice place was reachable by feet (tram 28 in less than 10 minutes, 1 funicular in 3-5 minutes, train station 5-7 minutes, main place (placa do comercio) in 20 min...). The inside is very clean and you will find everything you need and even more.
I thus highly recommend this place and would for sure come back here if we should plan another trip to Lisbon!
