Nuno is a great host, very helpful and welcoming, always in the mood for a chat. He gave me lots of tips on what to see and where to go in Lisbon. Definitely among the friendliest hosts I've had.
The house is perfectly located - you can easily walk everywhere from here.
The apartment itself is kind of basic/shabby, but it's clean. Even though the bed is just a mattress on the floor, it's very comfortable.
