This flat has a lot going for it, and we really enjoyed our stay. As the ad suggests, it is spacious, amazingly well-located, charming in its local touches (the tiles etc). Beds are comfortable, the showers are great. You can see the river, bridge and sunsets from the living room windows. The big table in the kitchen was appreciated and well used. The host company was very responsive, and answered our questions promptly and helpfully (we did not interact with the host directly, but rather a series of workers for a company that seemed to be managing the property). There were a few little missteps: the flat lacked some basics that were listed in the ad, as well as some that were not but that one would expect from an Airbnb - ranging from oil and salt & pepper to washing up liquid, dishwasher detergent etc. The absence of some of this, though not all, we were told, was related to COVID. Also, as another recent reviewer noted, the front WC has an off-putting smell, which the host company assured us would be looked at.
Overall, a good home base from which to explore Lisbon. We would happily come back.
