We arrived a few hours before the actual check-in, but were still allowed into the flat. Everything was very easy and unproblematic. José was already there and gave us great tips for restaurants, bars, museums and sightseeing. The flat was very clean and only 15 minutes by taxi from the airport. Bairro Alto is easily accessible by metro (station just around the corner), taxi (10 minutes) or on foot. We enjoyed our time here and really felt at home. Definitely recommendable, we want to come back.
