The location was amazing, the bed was super comfortable, it was just the right size, and was perfect for what we needed. Mark was wonderfully communicative -- just the right amount -- and clearly is a real neighbor, not just an investor-type. I would definitely have a staff member from out of town stay there again.
The only downsides were that a) it was quite expensive after AirBnB fees and city taxes, but that's not the owner's fault. And if you had more than one person staying there, the per-person cost would be fine; b) the upstairs residents were quite loud at random times of the day and sometimes during the night. Not a big problem, but worth mentioning if the person considering staying there is sensitive to sound or has troubles sleeping.
