Really nice apartment in the center of Lisbon. The aparment is really nicely decorated and many details to make it feel like a nice lived in apartment. The terrace is also really nice and is like an extra room when the weather is nice. Plants and flowers gives it also a more "homey" feel.
The apartment is also on a street that many tourists flock to take photos of the trams :)
For this apartment (and Lisbon) in general, you will have to like stairs. Normal though for old buildings.
All in all a really nice stay and nice easy communication with the hosts. I would recommend a stay here!
