We stayed one night at Maria's place (had to fly back to the US early the next morning) but the communication was great and check in was very easy. We picked Maria's place because it included parking for free - unfortunately when we went to leave the garage at 5 a.m. to head to the airport, it wouldn't let us out! We were able to go to the machine and pay for the parking and then let us leave. I've been in contact with Maria though and it sounds like it was just an issue with their parking tag so I think parking is normally free during the stay. We really appreciated the restaurant guide and it was nice to stay in what felt like a more local area of Lisbon (we stayed in the Bairro Alto area earlier in our trip). I would recommend staying at Maria's!
