Carly's apartment was exactly what our family of 2 couples and a 2 year old needed. It's a cozy apartment for 4 adults and a child, but the patio is a fantastic amenity and makes the place feel much bigger. The AC in the summer was a nice thing (especially for us Americans more accustomed to it), and the kitchen had all the essentials and then some.
Great location with easy access to main street for food and nightlife, plus bus and subway stops within 5 minutes walk.
Highly recommend for anyone looking to stay a bit away from the more touristy side of Lisbon, but still close to it.
