Ana & Mariana's cozy apartment was perfect place for a week in Lisbon for the two of us. The ground floor location was appreciated after long days of walking the hills of Lisbon. We found the historic neighborhood to be quaint, and at no time did we ever feel unsafe. As it is an older building, we were able to hear quite a bit of noise from the corridor, stairs, and adjacent apartments, but it was never an issue. Quiet hours are respected in the building at night, so sleeping was not a problem. It should also be noted that the hosts were very accommodating, arranging for us to check-in much earlier than 4pm. We'll definitely look to stay at one of Ana & Mariana's properties the next time we're in Lisbon!
