I had an awful experience in this stay. Do not recommend to anyone this apartment.
1) There's a problem with hot water. It's available only for 10 minutes. if you were a girl with long hair or 2 people, it will be a problem. At new year's eve I had to warm water in the stove to take a bath. Like living in middle age and my girlfriend had a cold shower twice.
2) The sofa/bed is impossible to sleep, seems like a black hole suck you to the middle of it.
3) After I had confirmed and payed, the host create a rule to control the temperature in the apartment, if it was not at 17oC she would charge me later more money. The apartment is very cold.
4) Also the owner made a claimed to pay 1.500 euros to buy a new sofa. She blamed me to break it, and it was already bad when I came. Impossible to someone brake a one inch tube.
5) 12 days after I left the apartment, she sent me a message saying there was a pipe clogging, I stayed for 8 nights, she used it for 12 and blamed me again!
She also sent me messages at 2am, and still disturbing me without any respect.
Also lots of small problems... 90 steps to get to the 5th floor, do not recommend. The sanitary is floppy, may break any time, and you might be blamed. She allowed (per writing) to use lots of stuffs (like cabinet, wash machine etc), but forget about it, and get angry later.

RUN AWAY of this place.

The host seems kindly in the first time, but later you confirm she will start create rules, and start to complain about the former guest (I guess I will be the next). Seems nice that she left a book with tips, but you HAVE TO memorize it at all, unless it's a kind of law, and you just have to obey or will be receiving bothering messages late at night in your cell phone for a long time.
Seems to me she wants to take advantage later from guests that stayed there.
