Elena was out of town so her aunt welcomed me to the house, and was very nice. Still, Elena herself was very helpful with both issues concerning the apartment and more general questions and requests such as transportation, etc. The apartment looked exactly like the pictures - modern and clean, and sufficiently specious.
I had two issues in the first day - the internet didn't work and I was given a broken key so couldn't lock the door - so the start was a bit "rocky", but by the next morning both issues were resolved, so overall this didn't effect the visit too much. I should mention that apart from the apartment's door, there are additional three doors to in the building, so I didn't feel insecure even when the door could not be locked. And again, there was just one night with this problem.
The shower was especially nice, with strong water pressure and both a douche and an overhead "rain" douche. As I think someone mentioned before, the toilet is a bit tight.
Two main words of advice before coming: 1) it should be noted that the apartment is in the third floor and there is no elevator. For me it wasn't a problem, but for others it might. 2) I don't know if the 35-38 degrees celsius I had in Milan are indicative of its weather, but staying in the apartment during the day wasn't really an option, with only fans and not air-condition. Luckily I did not plan to stay during the day, and the nights were fine.
But overall, the experience was very good, the listing and pictures are very accurate, and Elena was very friendly and helpful.
