I missed my train/bus and needed to stay one more night in SIntra. Booked this with no much reading. The apartment itself was nice and cozy. But in the middle of the most busy tourist area, so sound from the street through the windows.
Also a lot of noise from the neighbors entering and trough the roof from them moving around, ended up with earplugs.
Also no heating, but a lot of nice blankets.
It was ok for sleeping the night, but would never rent it for longer time.
