Great flat, I highly recommend! Very nice and safe neighbourhood in the heart of Lisbon's centre. Very close to a very good and cheap grocery store as well as the metro station. Walking distance to many city attractions.
Flat on its own is also very nice. High internet speed, well-equipped kitchen and generally no issues whatsoever with maybe an exemption of some very minor things like shower not having a very high pressure etc.
The host was also very friendly, accommodating and replying very quickly whenever we had a question.
