Lovely place in the heart of one of the oldest parts of Lisbon. Clean, comfortable beds. Everything you need for simple meals at home in the kitchen (including a wine opener!). The upstairs is very low ceilings as everyone has commented, but if you're sleeping up there it's not a problem or would make a fun place for kids! There was even a small clothes washing machine which was an added bonus. Beautiful, peaceful place to base your adventures in Lisbon from.
If you're like me and don't always travel with international data on your phone, you will want it for check-in to coordinate meeting at the door and getting the keys.
