The biggest positives of the apartment are its location, its décor, and the fact that Vasco is such a wonderful and attentive host. Vasco arranged for our transfer from the airport, kindly left a bottle of wine in the fridge to welcome us to Lisbon, and was very flexible when it came to check-in and check-out times.
It was quite loud outside in the early morning on the weekend, but that is to be expected given its prime location and the fact that the EuroVision semis and final rounds were occurring. The upstairs neighbors were also noisy at times. Nothing a good set of earplugs couldn't handle. The beds are set up so that they can be arranged as four singles, 2 singles and a double, or two doubles. That provides great flexibility, but a small gap can develop between the two singles when joined to become a double. If that ever happens, it is easy to eliminate by readjusting the mattress topper and pushing the beds closer together. We got the hang of it after our first night.
We really did love the place and urge other travelers to Lisbon who are looking for a good central location to consider it.
