This is such a charming little apartment. It is exactly as the pictures, well maintained and clean, and lots of little touches to make it easier for travelers. I am a women who was traveling solo and i felt very safe in the apartment and surrounding area. Super charming Alfama neighborhood, that is walkable to many different things. The hosts had excellent communication and even though my flights were super delayed, they still met me at 1am to give me the keys and help with a bag. The kitchen was stocked for an Airbnb - making it quite easy to cook. The bed was comfortable, plenty of storage for clothes and things, and the WIFI was great and reliable (I was working from there and easily able to do video calls and steam). Great cross breeze when you get the windows open. I highly recommend this charming apartment.
Just a few things to be aware of -
You can not drive up the building, those streets are cobblestone and only can arrive by walking. Usually you get dropped off at the Museo de Fado, and it's like a 4 min walk the apartment...it's not a big deal, unless you have a ton of luggage or accessibility issues. Same goes for getting into the building - it's on the first floor, and the staircase up in narrow).
The neighborhood is lively. There are a lot of restaurants near by, and Fado clubs. I personally loved hearing the singing and music from outside. It goes util about 12 some nights. It's not rowdy at all, but just there. I felt like it gave a very charming experience.
