The apartment is as described, spacious and gorgeous. The dinner table is awesome and we were able to enjoy an amazing NYE dinner. Location is great and you'll get everywhere in Lisbon in 10-15min driving.
Our hosts were very arranging on check in and prepared one room early so a person coming from the US could rest. Unfortunately we weren't able to leave our luggage after checking out, our flights were at night, and we lost an hour trying to find a place where to store them (the luggage drop close by was closed).
We all felt the apartment could have been a little bit more stocked with essentials, especially at that price (no oil, salt, pepper, only hand soap in bathrooms).
Overall we had a great time staying there and visiting Lisbon, I highly recommend for any large group of people!
