I would not find any better place for Lisbon. It's in the center of "real" Lisbon. Everthing is in the walking distance. and if you go far, you can get 28 tram which is 2 minutes walk from the house.
Jorge is really the best host. He give us every detail information, and when there is any problem in the house, he fix it immediately.
and please don't miss Jorge's music. He is the real musician, you can find it on wednesday in his brother's restaurant. if course the food is one of the great in Lisbon.
totally, Jorge's house will be the best choice for Lisbon.
