The apartment is cosy, clean. Unfortunately, the person next door is a pianist/opera singer who starts rehearsing very early in the morning (8.30). She has a beautiful voice and plays the piano wonderfully, but it's not exactly quiet.
The area is beautiful, close to different metro stations and there are shops and restaurants literally everywhere.
A little tip for the owner. It's called Air B&B, where the first B is Bed and the second is Breakfast. Having paid more than 700 euros for 4 nights, I would have expected at least 1 coffee capsule a day per guest. I'm not saying a full breakfast, which would have been nice, but at least coffee and water. There was absolutely nothing but a box of left-over tea from some previous guest. Just some coffee and a couple of bottles of water in the fridge would be a nice touch for your guests.
