We stayed in this place for 5 months and it was a fantastic place to stay.
It's very nice - the patio is lovely, the main room is very spacious, and everything is modern and clean. It is an awesome location close to lots of great restaurants, parks, and public transit. The host, Maria, was very available, helpful, and attentive to our needs. The one big issue we had, which is the sole reason it is 4 stars instead of 5, is that the air conditioning in the bedroom did not work. If turned on, it would make very loud sounds that would continue even after it was turned off. Maria did send someone to try to repair it but those efforts were unsuccessful. There were times it was very hot in the summer, and the broken AC was quite frustrating especially since the place was very expensive relative to other Lisbon properties. If the AC gets fixed then I'd recommend this place without hesitation.
