The apartment is perfectly located in the old town and has a beautiful sunrise view over the ocen. There is a nice restaurant right outside. The rooms where clean. The only problem we had was the clogged sink in the shower, wereby water was draining very slowly.
We visited Lissabon at the end of february and used the electric heating in the apartment a little bit in the morning. But overall it was very warm (over 20° Celsius) and not so many tourists around. We enjoyed our stay very much.
The easy and friendly communication with the host beforehand was pleasant. =)
