The location is very central, close to the metro line and tram 28, and lots of restaurants and ammenities however it can be loud at night with partygoers, and I wouldn't reccomend it for light sleepers. The stairs are very steep and can be a difficult climb for some, but were okay for us.
You cannot use major electrical appliances (air con, hair dryer, etc) all at once given the historic area and electrical restrictions being in such an area (this may be typical for the historic areas but I am not sure), so this is something to keep in mind.
The hosts are very kind and responsive and were very easy to get a hold of. The check in process is very easy and they have a book of reccomendations. It would be ideal for a family (2 parents upstairs and 2 children on the main floor.
Thank you, we had a lovely stay in Lisbon!
