We only spent one night at the apartment, but it was really fantastic.
The apartment itself is very pretty and was very clean. There is enough space to unpack the luggage. The apartment is well located, as you can walk to the center within 20 minutes but only have to walk 10 minutes to the train station Santa Justa as well as to the bus station, from where the bus "EA" takes you quickly to the airport.
The host was very friendly. Especially, as she agreed, that we could only spend one night at the apartment and that it was no problem to leave the apartment early in the morning.
I can recommend a stay at the apartment.
