The location was perfect, the apartment was clean and tidy, just what you can expect from the pictures and Jb was very nice and available at all times if you have anything to ask (I had problems with a lock but Jb helped quickly). I visited during a festival in Alfama so I could hear the music from the street very clearly until 2-3 am, but it was fine because I was so sleepy after a whole day of walking around Lisbon, I think it was only that weekend. The city is super beautiful!
