Paulo is en excellent host, gave us a lots of advice where to go and where to eat in Lisbon and even helped us to get a taxi (early-morning-flight).
The apartment is perfect to stay for 2 persons and there's everything you need especially in the kitchen. the Pocket-wifi is perfect and really helpful! Only problem was some bad smell from the bathroom but Paulo will have it checked soon.
the apt is near to the city center and main attractions and at night it was very quiet!
