One word: perfect!
The apartment is really nice, superclean, the bed is really comfy and well equipped with everything you may need. Recently furibshed and spacious. The bedroom is not in the front part of the apartment so no noise to sleep :)
The neighbourghood is amazing, with a lot of restaurants, cafés and a supermarket really close. Very well located to discover the city.
Pedro is a great host, arranging everything we may need and giving us a lots of tips for our stay. He's really nice and friendly...
I would come back at Pedro's for sure! If you go to Lisbon this is the place to stay.
