Matt's place is in the historic section of Lisbon known as Familia. It was nicely updated a few years ago. The unit was laid out as a very comfortable one bedroom apartment. It has all the amenities. The major drawback might be that the primary tourist locations are some distance away for those on foot. Parking in the area might be a problem - even on the streets - if one is arriving by car.
Lisbon is known as the city of seven hills. It is difficult to get from one area to another without having to travel up or down rather steep and narrow walkways. Balance that with the very positive disposition of all who we met there.
