This is a fantastic apartment in an ideal location. We walked to everything that we wanted to see and do and had a wonderful time.
Our only complaint, and it has been stated by others, is that neighbors can be heard. Music was playing one evening at 2300 and another night at 200. If you are sensitive to noise, I recommend bringing earplugs.
That being said, we would definitely stay here again. To be able to be in the middle of a world class city and stay in a modern apartment situated in a historic building, you need to be willing to accept a challenge or two.
