The place is brand new and very tastefully decorated. There is clearly a true luxury feel.
The check in process is hassle free.
The location is perfect. The building is gorgeous and there is 24/7 concierge.
For longer stays though, like mine, there should have an extra cleaning and change of sheets. It seems that it is never included regardless of the length of the stay, which is clearly an inconvenient. I asked the question and didn't even received the courtesy of an answer.
Also, there are no curtains nor blinds of any kind in the living room so if you are more than two and intend to use the sofa-bed, you will have full light all the time, natural or artificial, as the building façade is heavily lit.
On this chapter, and maybe this is the only real inconvenient of my stay: the blind of the bedroom is not black out at all, and you see very clearly in the room at any hour for the reasons mentioned above.
All in all a great choice for shorts stays.
