I, too, was "upgraded" to a different suite that was nothing like the one I booked. The replacement suite had a terrace, which was nice, but the patio door did not lock. Neither did the door to the building; there was a lock on the door to the compound and on on the apartment itself. If security is a big concern of yours, this is not your place. Other than that, the apartment I was given was extremely well-located - close to Avenue Liberdade yet secluded enough to be quiet. The apartment was clean, had everything I needed and João was very helpful with an extensive list of by things to do around Lisbon.
