When staying in Lisbon you MUST stay at Rui's place- not just to enjoy the great location, amazing home, and extra special hospitality, but to also meet the friendliest person in the whole area!
We loved staying at Rui's for the three nights we were in Lisbon and enjoyed the long conversations we got to have, sometimes with the help of google translate :) The house is very stylish, the pool is awesome (though weather didn't permit we used it), and coffee awaits every morning. Rui was very kind, patient, and generous with his tips. We felt completely at home and will definitely be staying here again in the future.
Highly recommended!
