Perfect location right in the heart of Alfama (be aware of stairs, though!), and a super comfy place with a special vibe.
It has issues with warm water, though. The water only gets warm for less than 10 min every few hours. If you are two and want to take a shower right after the other, whoever goes next will have to take a cold shower. Also, no chance of a good long warm shower after a long day walking around the city.
