We enjoyed our stay at the apartment very much. We could reach everything in a few minutes and had the chance to explore everything in Lisbon.
The apartment was very comfortable and we liked the modern style a lot. It had enough space for three persons. The check in was easy and went without problems.
We only had the feeling that the floor and the couch were a bit dusty. When you plan to cook, you have to consider, that the equipment is limited. For example, scissors or oven mitts are missing.
But these are some minor inconveniences.
All in all we can recommend the apartment for your stay in Lisbon.
