The place was great! It was very clean and spacious. The location was excellent as it was right near many bars and restaurants and easily walkable to the rest of the city. The on thing is that it could be a bit loud at night, especially on the weekend. If you're planning on going to be early every night it may not be the best location for you. If you want to go out though, then it's perfect.
João was a great host. He was happy to give lots of tips about Lisbon and even welcomed us with a free bottle of port! My friends and I would be happy to stay here again next time we are in Lisbon.
