This place is outstanding.
It is small, but more than enough for one visitor or a couple.
Location is excellent and it is well kept and clean. The only downside if you are carrying heavy luggage, is that it's on a 4th floor; otherwise it should not matter as the place is perfect.
Communication with the hosts was always very clear and easy, and they were very gracious and flexible with my check in and out times.
The hosts left a bottle of wine, chocolates and oranges and a portable WiFi which was very helpful.
Definitely a great place to stay when visiting Lisbon.
