I only got to stay here one night, but I greatly enjoyed my stay at Sara's.
The room is cozy and cute, the bed and linens are VERY comfortable, and I liked the decor throughout quite a bit!
Communication was excellent, and Sara was flexible even when I wasn't able to make my original ETA, due to bad timing with public transportation.
I know Sara had a number of great recommendations for visitors to the city; I highly recommend her place, whether or not you know Lisbon.
