Negative- Kristiana's apartment is on the 1st floor. There is a noisy night bar at the ground floor which we were told about only once we reached the property. The bar played music until 3:00 am on 2 out of the 4 nights we stayed. It didn't put the music down despite few reminders. Despite of closing all windows it was still not so easy to sleep unless you are partying yourself until that time :)
So while it's an excellent deal in every other way, the night club was bit of a deal breaker.
