We lived in this apartment for 2 months and had a good time there.
In our opinion the apartment is better than the pictures show. Even though it is an old building it is fully renovated. It even has a “real-estate agent” view to the river and receives lots of light. We stayed during winter months and the apartment was not cold as some apartments in Lisbon can be at that time.
Staying 2 months of course meant there were small things we were missing. But the main thing was that we would have liked that the contact with the owner was a little quicker. She responded fine and was very friendly and got the things fixed without a problem. But especially one time when the internet disappeared was important for us as we had to work from the apartment. A quicker action would have solved the problem almost immediately.
All in all we were happy there and would consider this apartment again if we return to Lisbon.
