First of all, I completely recommend this appartment and I would go back. Federico, the host, received me at 8am because my plane arrived around that hour... so I didn't had to go work in a cafe until the check-in hour. And also he made the checkout process really flexible too.. so, THANK YOU FOR THAT!
Now, to the review: This appartment is great. A nice sofa, big table with strong chairs and a big and confy bed.
The internet connection was OK to have videocalls.
The bathroom is OK, it's not the biggest that you could have.. and the heater is a little bit slow when you want to take a shower. But if you wait some minutes the water starts to get hot enough.
The kitchen has several appliances which is really good.
On the other hand, the elevators are kindof small and old, but there are two so it's not an issue. I actually never bumped to anybody else in them.
Overall, it's a good appartment. Btw, the train passes in front of the appartment once or twice every hour (around like 7am to 10pm)... for me it wasn't an issue, it wasn't that noisy.
