Rui was a fantastic host. Communication was easy and quick, and he allowed us to get into the apartment at 1pm as opposed to 3pm. He had a friend come meet us and show us the apartment since he was unable to. The apartment itself is small but clean and in a fantastic location with plenty of good restaurants and Fado restaurants in the immediate area. The view of the River from the apartment (specifically the bedroom) was great. There was a bottle of wine awaiting us, recommendations for places to eat in the guest book, a few books on Lisbon, and a map which we definitely appreciated.
Only 3 things to note is that the apartment is really small (as described and mentioned in previous reviews) and only had room for us 2 and our 2 small bags. The bathroom and shower is tiny as well and didn't have much hot water (only about 10-15 minutes worth total). The front door sticks a bit and the stairs up to the unit are very steep. But all in all nothing that wouldn't be expected in an older apartment building in a very densely populated and old part of the city. Would absolutely recommend this apartment for a short stay for 2 people!
