Our stay was fairly good! We didn't get the unit number until after we were already in the building. Coming from another country, we just expected all the information to be given to us beforehand. We were given the option to pick up the keys from the office or given an exact time of arrival - we were driving up from Sintra, so we chose to pick up the keys at the office (which was a seamless process and the woman was lovely). When we got into the building we realized we were not given the unit number - it was 11pm. It was a bit frustrating, but after 10-15 mins the host responded to give us the unit number. Once inside the unit there was a manual, but there was no wifi password so you do have to ask for that.
Overall, the apartment was very nice and quiet. Just the communication & information that was not given beforehand could be improved.
