Positive points:
The apartment is exactly as pictured and described; It's really neat and new. The matress is good.
It is a quiet apartment, although in / next to lively district.
Their is an aircon that I used to heat the room (cause it's a bit cold in the evening) and it was just fine (I had slippers and I would recommend to take one with you, especially if you're travelling during winter months).
The bathrrom is small but there is everything you need - everything is clean and new !
Communication with David was easy.
What can get better:
Apparently, there was a wifi problem when I was there, and I couldn't get access on internet.
I would recommand no entrance in the appartment apart from checkin / checkout.
