Three of us stayed for a week in Pedro's apartment. It's in a fantastic location and has everything you need for a sightseeing trip. The kitchen had a lot more equipment in it than most air b and bs which was a bonus. We made use of the terrace in the mornings. Pedro was a fantastic host, making sure we had everything we needed and dropping off some extra keys. We really appreciated the tips on where to eat.
It is quite loud at night, but that is true of everywhere I've stayed in central Lisbon, and easily remedied with ear plugs. Just remember to take some if you're a light sleeper.
