The place is well located with good amenities for the 9 nights we stayed there. In the big room, during the night you could hear quite a lot of noise from people walking upstairs which is not great, but otherwise I cannot fault the place.
During our stay, on the last day, there was a situation where a stranger was inside of our apartment (which we still didn't understand how that happened as the door was closed), which we were very bewildered and I immediately called the host and explained the situation and they immediately came and changed the locks of the door and gave us a new set of keys, which I was thankful for.
Overall it was a nice place to stay in Lisbon :)
