The location for this apartment is great for visiting the downtown attractions (Hall of Fame, Broadway, etc). It is just far enough away that you don't get the Broadway noise, but still very convenient to walk to. There are also a bunch of great restaurants nearby (and Parlor Donuts across the street with great Donuts and coffee!). The unit is spacious and has a great balcony overlooking the pool area. The pool got VERY crowded on Friday afternoon (we were there Wed - Sat), but was not noisy in the evenings. Despite the crowds, we still went swimming every day and my kids loved it!
Katherine was HIGHLY responsive. She addressed any issues we had as soon as she could. If you stay at this place, I recommend that you contact her if you notice anything or need anything, because she will go out of her way to make sure you have a good stay.
Other guests have commented on the Latch App system that the entire building uses for unlocking doors, and I must say that we found it very easy to use. It was convenient (just use your phone) and was very secure!
The Burnham seems to be a really good place for adults to stay, but perhaps not as great if you are staying with your family over a weekend. We were there with 2 adults and 2 kids, and earlier in the week, the pool was not too crowded and the other guests were not too rowdy, but on Friday, the vibe of the place shifted to be more of a "Bachelorette weekend". The noise level in the unit (even on the more rowdy Friday afternoon) was very low (seems to have good sound-proofing). The building has a lot of great nooks and crannies to hang out (lobby, roof-top deck, pool, patio, etc), and this was really nice.
