We had the pleasure of staying at Antonio’s flat for 5 nights. The location is in a great neighbourhood, with easy access to regular transportation ( metro, train ) and tourist access (Tram 28, Tuk Tuks, hop on / hop off buses, etc.), as well as, shopping.
The flat is great. Not too small, great bed, good shower, good kitchen, wonderful views and quiet. Very comfortable. It is on the 4th floor, so there are quite a few narrow stairs to negotiate. It is a workout, but we got used to it after 1 day. It will help with all the climbing you will be doing in Lisbon anyway!
Antonio was a great host. Very responsive in communication, met as at the flat late due to our flight being delayed, showed as around and how to operate in the flat, recommended a nice restaurant which we went to twice, and told us where to go locally for groceries, etc.
Would definitely recommend staying at Antonio’s place.
