Carolina's flat is in a fantastic location, and is huge, with two balconies! She has so much style and good taste and it felt very warm and personal, it was so nice to live as a cool, bohemian Portuguese artist for a week!
Because it's such a great location - right by the Cathedral and bridge - the street noises can be very loud at night, especially at weekends, but nothing that a couple of earplugs can't resolve.
Check in was quite late, at 8pm, but you can leave your luggage at São Bento train station which is a minute away, and still have time for a quick Wine Cellar tour beforehand!
This place was so lovely, and such good value, I thoroughly recommend it.
