The apartment was very nice and clean to a reasonable point, the room is very spacious and overall perfect for my needs, position is just perfect, 5 minutes walk from the main subway and in a nice neighborhood.
I had some issue with the other current guest, who forgot the keys inside the apartment twice, and I was the one who had to solve the issue even though I was out for work.
Another issue was with the electricity that went away for half a day due to unpaid bills (It can happen, everybody forgets something once in a while), it was resolved once I made notice of it.
