My wife and I just finished a 2 week stay at Catarina's apartment in Lisbon. We had a wonderful time in the apartment and the location is absolutely ideal for exploring Lisbon!
The location of the apartment is close to some of Lisbon's iconic tourist spots, but yet not right in the center of them. Bus, train and metro access from the apartment is only a few minutes walking distance away.
The apartment is modern and very comfortable. There are many restaurants around the apartment to chose from, but if you want to cook the apartment is fully functional for that as well.
Communication with Catarina was also very easy and very generous on her part. We would both highly recommend choosing Catarina's apartment as your Lisbon address for anyone considering it.
