We stayed at this apartment in February - cold, snowy, blustery, slushy February! It was walkable to great sights and restaurants, and provided a great base for our wanderings.
The good: Very clean - floors, kitchen, bathroom, all! Location was great, too, but keep in mind that being close to tourist attractions also means that it is close to crowded places. :) Check in was easy and the bed was comfortable.
The not-so-good: Check-in required emailing pics of id. As I do not like sending id via email, I would not have chosen this place had I known of that rqt.
The entire building had a very strong smell of artificial room freshener - those with fragrance sensitivities beware!
