We spent 10 days in Lisbon, and we have a great time in Pedro's house! The flat was clean and it has everything you could need. The house position is perfect to visit the city center, near to the metro and buses; the host is very kind and he will give you lots of advice about restaurant and the city itself. The street noise is quite annoying, but only with windows open; the room was a bit smaller for 4 people, but comfortable, especially beds. Remember that kitchen, living room and two bathrooms are shared, but they're always clean and there's enough space for all the guests. I really recommend this place for a trip in Lisbon!
