It was very easy to find the apartment thanks to Arianna's directions. Once there, her brother was waiting for us to give the keys and show the apartment. It was very clean and just like the pictures! There was some food (fruit, coffee...) and all the basics, nothing missing! The area is very calmed, close to the metro station, 3 supermarkets near (one of them just in front), and also some restaurants.
Everything worked well (heater, water, kitchen...), natural light in the whole flat during the day, and a lot of blankets, pillows and towels provided!!
It was very good that the check in and out hour was flexible!!!
Thanks for all!!! :)
