Carolina's place is amazing! A cute tiny house in the historic neighborhood of alfama. The space is perfect for a family or group of friends of 4 or 5 people. The house was cleans and neat, the location is of easy access to touristic places in Lisbon and there are bakerys and restaurants close by.
The only thing I'd add is that if you are a tall person maybe the 3rd floor bedroom would be a bit uncomfortable. The ceiling has a triangle shape as you see on the pictures and is sometimes a bit low. For me and my boyfriend was fine because we are short, but I imagine that would be complicated for someone taller. The rest of the house is fine though.
Overall our experience in Lisbon was great in Carolina's place :)
