I highly recommend Antonio's flat for a stay in Lisboa !!!! I would definitely go there again.
I went there for a few days with my family and everything was perfect : Antonio waited for us at the apartment even if we arrived late, he welcomed us with a bottle of wine, olives and strawberries. The flat was clean and large, enough space for 5 people. It is situated in the vibrant Bairro Alto, but in a quiet street ! It is close to good restaurants, bars, shops and supermarkets.
Antonio was very responsive to all the text messages we sent him and gave us good advice. One little thing : if you come by common transportation with luggage, the streets climb a lot to go to the flat, but my 80-year-old grandma could make it! Otherwise take a taxi.
Thank you again Antonio !
