We were four friends from the US staying in Lisbon for two nights before heading to Lagos.
Positives: excellent location in close walking distance to main attractions, bars and restaurants. Catia met us right on time and was very nice explaining the city and giving us great recommendations to eat. Communication was easy and they were flexible to let us check in earlier. WiFi worked well.
Negatives: Lisbon is an old city and this is in the old town so all should be taken with a grain of salt but there were some things to be aware of. It’s tight for four adults. The downstairs bed is a US double. Upstairs there are two twin beds and the bathroom. The upstairs ceilings are sloped so you will probably hit your head at least once. We were four women so it worked but I think a tall man would have a tough time in the shower and generally navigating the upstairs floor (inevitable since bathroom is there). A few things felt tired - the downstairs bed and couch bed were not comfortable. A light was broken upstairs and there was a musty smell throughout. Lastly while you’re not on the loud road some of the bar crowd filters over to the street and there is noise late - not a lot but enough to wake up a light sleeper.
Other: the flat is located on a big hill (as is typical in Lisbon) so best to cab or uber when arriving if you have bags
Overall good value for money, great location. Would recommend for a few nights if you are just looking for a place to sleep mostly. Airbnb doesn’t allow for 3.5 rating but that’s probably most accurate.
