We stayed in one of the 2 rooms available to rent from Hugo. The room overlooks a street which at night got really noisy. I'm sure this depends on the time of the year and the activities taking place in the city but we had to wear earplugs and keep the window closed in order to get some sleep. I read some other reviews which mentioned that the room was very quiet so I think we were just unlucky.
Everything else about the trip was good. The communication with Hugo was good and his instructions on how to gain access to the apartment were clear.
The apartment is located in a great part of town and close to lots of things. There is no breakfast offered but there is a great cafe steps from the apartment called Fabrica. We can also recommend Toma Lá Dá Cá and Pharmacia to eat dinner at. About a 20 minute walk from the apartment.
Lisbon was a lovely city to visit. Cheers!
