I spent an entire week in Lisbon and stayed in the smaller of the two rooms in the apartment. Everything was clean and matched the description. I only have two minor complaints: 1. The room's window is currently broken and can't be opened to let in fresh air (Ana and Hugo are aware of this and are going to get it fixed soon). 2. The mounting for the shower head in the bathroom is loose and doesn't hold the shower head so one has to hold it while showering. This wasn't really an issue for me, which is why I even forgot to mention it to Ana and Hugo.
Also, at this time of the year it can get quite cold in the apartment but there was a small heater to warm up the room.
The apartment offers everything you could possibly need and its perfect location right in the heart of Lisbon for a very fair and affordable price make it a good choice for an enjoyable stay. If you're not too tall and don't mind climbing the stairs to the 5th floor, I can absolutely recommend this place.
As for Ana and Hugo, they are what I consider to be the embodiment of Airbnb's philosophy, being absolutely exemplary hosts that really welcome you in their home and let you participate in their lives. They are sweet and caring and will always be there for you if you have questions. As I was out exploring the city most of the time, I didn't spent that much time with them, but when I did, it was like being with friends. I'm glad that I got to know them and they made my stay all the more enjoyable.
