We absolutely loved our stay here! Plenty of space for 5. The apartment was clean and stylish and they had great amenities including several extra electrical adapters if you forgot yours/didn't have enough.
The check in process was easy and they left us a bottle of wine as a welcome gift!
The location of the apartment is absolutely fantastic. You're a 10 min walk from the ocean and very close to other attractions around the city.
We would highly recommend this location for your stay in Lisbon.
