The apartment is in a fantastic location but be aware that taxis or cars cannot get in the street so you have to be able to haul your luggage up or down many steps. This makes the apartment more interesting though I think! Communication was great and we had no problem getting the keys.
The apartment is clean and exactly as described. The little restaurant outside was very cute and nice spot for a nightcap.
Great spot for staying in Lisbon and I would definitely recommend.
