We had a great time in Paulo's apartment. First, Paulo is a wonderful host and very communicative. We really appreciated his guidance on the city and the apartment. He had everything prepared upon our arrival and we went through the map with him.
The apartment was clean and perfect. We had everything we needed and had a comfortable stay. The AC worked very well and cooled the room down within minutes which was very important to us while traveling in the summer. We didn't end up using the washing machine but it looked fairly new and easy to use.
The bed was very comfortable and we slept so well here. We also really liked that the windows had shutters so if you want the room to be a cave, this is certainly achievable.
The bathroom was clean, Paulo had a hair dryer which worked very well. We also were very happy that the shower had good pressure.
The apartment is centrally located, on a popular street full of restaurants right next to the main square. This however, was not a problem when sleeping as the restaurants usually close by 11 and the windows kept out any sound. The train station is also right across the street so going on day trips was very convenient. Paulo also notified us that the building next door was nearing the end of construction and they were breaking down scaffolding. We were worried this would start early but the law doesn't let work start before 9am which was great and we still didn't hear anything afterwards. Again this will probably be finished by the end of June so not an issue for any future guests.
Overall we loved our stay at Paulo's apartment and will certainly be back on our next visit to Lisbon. We will be recommending this to our friends as well.
