I booked the apartment on the same day, a few hours earlier, and the communication was great! I was even allowed to enter an hour earlier than 4 pm, which was great :) The checkout was at 12, which is a bit of a bummer, but I was first asked to leave at 11 and they gave me an extra hour, so I only have good feedback! The house itself was great and better than advertised! A very quiet street in the middle of Lisbon and a good stay overall :)
