This place is great for a couple (as the living/kitchen area is quite very small), if you are coming for a short period of time and on holidays!
I wouldn’t recommend it to work remote/from home as there isn’t much (or any) natural light coming in.
The flat is well renovated and pretty, but be aware that it’s located in a old building of Alfama, it can be noisy and smelly... But I guess, that’s the charm of the old Lisbon! :)
Down the door there is a little Fado restaurant giving the flat an unique experience.
