Great place for a short stay in Lisbon for one or two people. Location is perfect - 5 min walk to Carnide station (blue metro line) and 10 min walk to a Lidl. The studio is very pretty and clean, wifi was fantastic, bed pretty good too. Fair warning: it gets very hot inside the flat during hot days (to be fair it's been unusually hot in Portugal this year), it's a very small space (it has windows but only close to the ceiling), there is no washing machine or AC.
All in all, great stay. Ana is a fantastic host and very quick to reply.
