We spent a week exploring Lisbon as a couple - the flat is very suitable for this purpose.
The flat is well equipped and communication with Sabrina is impeccable.
There is a small supermarket nearby as well as cafes and restaurants. Tram and bus are close by, otherwise it is about 20 minutes walk to the city centre.
There is only one window for ventilation, but at least there are two fans. Unfortunately, you can clearly hear the neighbour from upstairs.
Overall, we felt comfortable here and would book the flat again.
