Great space for something very central, and a perfect location to walk to offices and restaurants, etc from. Plus place stays cool on very hot days with fans and windows. Early on I would have given this all 5's.
However latter part of stay, doors of other flats often slammed at 4-5am and neighbors had a house party one weeknight well into the morning which made the next day rough.
Flat itself is good overall and the hosts were very helpful and got back in touch the day after the incident as well as same day on other requests (front door lock broke for one example). Perhaps just had bad luck with that place.
