The place is perfect. I cannot find any other words.
The location is great, right in the heart of the historical part of the city. Very quiet and safe. Close to many places of interest, including the well-known tram route #28. Two train stations are also within walking distance, which can be helpful if you plan to travel to other cities.
The apartment is huge, very stylish and decorated with a taste. Very comfortable bed and amazing view from the bedroom as a bonus. The kitchen is fully equipped, we never missed anything even though we used the kitchen every day.
We were met by Rui, very positive and nice person, who gave us a lot of recommendations.
We couldn't have found the better place to stay in Lisbon.
