This was easy to get to and Matteo's friend greeted us upon arrival. The hosts were very accommodating and responsive, and we had no problems at all with the apartment.
The area is very well located need the tram and metro, and was perfect for both touring and getting away from the noise. Lots of good restaurants nearby and the apartment was clean, large, and comfortable.
The bed was probably a queen but it felt a bit short, though I believe it is a standard size in European homes. To get to the bed there is a steep staircase which was a bit tricky to climb, particularly in the middle of the night, but it wasn't an issue. Also the bed is in a loft which was about 5.5 feet tall, so we had to be careful getting to bed but definitely not a problem.
We really enjoyed our stay and highly recommend this apartment.
