We stayed at Joao's place for three nights. Joao's place is very new, so everything is new and clean. The bed was very comfortable. The kitchen well equipped. We felt the security was excellent in the apartment and parking lot. Also, the location was great for us to walk to all the sites in the area.
Joao greeted us upon arrival and met us again when it was time to leave. I highly recommend Joao's place in Lisbon!
