Lovely flat in perfect location along with good standard nearby restaurantes with the nice view (especailly in the morning).
Slight concern for us for living 3 days in this flat would be the following.
1) The key was very stiff in lock, it took us at least 5-10 minutes to enter and to leave the flat.
2) Unable to store luggage after check out.
3) No heating system in the flat and it was chilly and cold in November time.
4) Availability on late check-in would add the value. We had to use the "transport system" costing 30 euros from the airport, to ensure the check-in.
The experience could be better in a way; however, the host was really good in communication, and it was overally lovely to visit and travel Lisbon and staying in this flat.
