I stayed in this apartment with my boyfriend for a few days and I have to say it was impeccable! We didn't get to meet Joao unfortunately but we were always able to communicate smoothly and he was kind enough to let us leave our luggages there before the check in time as we got there a bit earlier. The house is perfectly located near Barrio Alto area with all the main attractions of the city within walkable distance. You'll find anything you need, clean towels and hairdryer were provided too, and definitely came in handy. There's also a guarded parking lot close by, which was very convenient for us as we rented a car and finding a parking spot in central Lisbon can be a pain. We definitely enjoyed our stay and I would definitely recommend it!
