After booking Patricia's apartment in Bairro Alto, she was in constant contact with me to ensure we would have a pleasant stay. Once we arrived, Patricia was there to let us in and make sure we had everything we needed. At one point, we couldn't get our key to work, but Patricia was back within minutes to sort it out. (It was our error, of course)
The apartment was comfortable and located in the heart of Bairro Alto. A lot of people warned us about the noise, and we were expecting a Bourbon Street level of activity... in reality, there were some people passing by late in the night, but it was not at all bothersome.
We were close to everything in Lisbon and felt really safe here.
