Self check-in was a breeze with the lock box. Apartment was clean and response to all my questions were quick. I locked myself out once (so don’t ever forget your key when you leave and they couldn’t use the spare key to unlock as I left the key in the keyhole on the inside, was an expensive lesson calling a locksmith on a weekend night!!) but everything was managed on our behalf and by the time we got back from dinner, the key was in the lockbox and we didn’t have to wait around trying to get back into the apartment. I definitely recommend this place, very central and close walking distance to the train station if you are taking the train to/from Lisbon.
