Staying in Luis's apartment was a pleasure. The apartment itself is clean, bright, spacious and well-equipped. Everything is clean, and the beds are comfortable.
After we booked Luis took all our flight details to ensure that there would be someone to meet us at the flat when we arrived (Patricia), and even though we were there early in the day, we were allowed access to the apartment with no fixed check-in time which was very helpful.
Luis sent very helpful information about how to travel from the airport, as well as a map for the taxi driver. Patricia met us at the flat and was very helpful with local information and tips. On our last day we were allowed to leave our luggage in the apartment because our flight was later in the day which we really appreciated.
The location of the apartment is perfect, in walking distance from central Lisbon with a variety of restaurants and bars around. I would definitely recommend staying here.
