If this is your first time in Lisbon the location is convenient. The neighborhood is away from the central tourist areas, but a close walk. The tram and bus lines also stop outside the building. This may be an issue for those sensitive to noise as two of the bedrooms are on the street and the windows are pretty thin.
The layout of the house is good for groups the kitchen and dining/seating area are separated. However, there is very little airflow circulating through the house even when the windows are open. We would recommend that the host provide some fans.
Lastly. While our the host was our initial point of contact, they are not there to assist you personally. This Air bnb is run by the equivalent of a property management co. We were missing towels and pillow cases in the third bedroom and the company seemed confused about our request and never showed up with the correct number of linens like they said they would. I prefer staying at Airbnbs where the host is available, it usually means that issues don’t have to be addressed through third party channels
