Kumail's Belltown studio was perfectly located and walking distance from pretty much everything. He was extremely responsive and helpful in the months leading up to our trip when we had questions - very easy to organize with, and he waived his usual fee for more than 2 guests, which we really appreciated. The place looked more or less the same as the pictures.
We were somewhat disappointed with the presentation of the place as it seemed like whoever cleaned left before fully finishing (I had to dump out and throw away an almost full coffee cup that had been left, perhaps by the cleaner, so it felt like I was cleaning up after whoever it was...) Being right in the heart of the city, it was rather noisy, which was to be expected, but the heater, which we never used, also made a terrible racket and woke us up every night (even through earplugs, which I wear to bed anyway), which was unpleasant.
Overall it was a decent place to stay but I think we could have found a hotel which was just as central, for a similar price, which would have had more comfortable accommodations and acceptable amenities.
