Carolina's place is lovely - nicely done out, very clean. Carolina was very prompt to respond to my messages and also generously allowed us to leave our bags at the apartment after check out as our flight wasn't until late afternoon. She also left some wine and pate for our arrival which was a lovely touch.
The only thing to note is that it is up several flights of stairs and also accessing the building is up a lot of stairs/hills which might not make it suitable for everyone. Not unusual for Lisbon as it's such a hilly place but worth noting.
