We stayed at Joao's apartment for 4 nights. The place is located in a quiet neighborhood that is still within a 5 minute walking distance to the old town of Lisbon and other places like bars and restaurants. The apartment had everything we needed. The house is quite old so you can sometimes hear the noises coming from the upper floor and during winter it can get a bit cold, but there are two electric heaters inside we were able to use. Joao and his wife gave us a very warm welcome and provided us with useful information. Overall we had a very nice stay and we can recommend it!
