Amazing location. If you want to enjoy the night life of Lisbon, this is the place for you to stay. The are has tons of bars, restaurants, clubs and shops at a walking distance.
João is an outstanding host. He is a quick replier and a very friendly person.
The only downside of this accomodation is that there is a shop across the street and some people stay outside speaking loud the whole day. But this is also what makes Bairro Alto a friendly, vibrant and lively neighborhood.
