Staying in The Blue House was a great experience - the flat is clean and well maintained. It's very well located in Lisbon, really close to a metro station so it's easy to get to from the airport via metro. It's also really close to the center of Lisbon. Check-in was really smooth, as Ruth waited for us to arrive and let us in and show us around. One thing to be aware of: the flat is on the top floor of the building, so it's quite a climb (~100 stairs) to get up there. Other than that, the apartment was a great choice for a short stay in Lisbon.
