The house is perfectly located to attend events at the Lisbon Congress centre by a few minutes walking while far away enough to live in a neighbourhood of residents with places to eat, drink or shop nearby. Belen is also a nice walk and the city can be reached by a direct frequent bus (I think 728).
The house has a lot of character, is nicely designed and all equipment is new.
The host Frederico is very kind and supportive and fast and efficient in all communications. I would want to and hope to return some time! Highly recommended!
