The location is perfect - bars, restaurants, great for exploring a nightlife, but really loud from the streets, I'm not a party person and trouble sleeping even with earplugs.
There is a heater, but was chilly (maybe just me, wasn't lucky with weather).
The host is living on the same floor, you won't have any problem with a check-in\out. He was really friendly, helped me to carry luggage on the 3rd floor and was checking on my needs. I was happy with no rush on the last day, I stayed in until 1pm and leave my luggage there for another a few hours.
The studio was clean on the first hand, but still a bit dusty on my opinion.
I was eating outside and didn't plan to use a kitchen, but the items there looked not good, and I don't think it was washed in between guests.
Anyway my staying was okay, the bathroom was clean, it was always a hot water and if you are planning a short stay it is an okay place for its money.
