Stayed here with my wife and our two 5-month-old twins. Greg was friendly and communicative. The location is really fantastic. We found free street parking just a block or two away. The stairs leading down to the basement are very narrow, and not great for moving car seats or luggage up and down, but that's no biggie. The sheets were washed and there was no trash anywhere. We slept fine, and didn't have any problems with outside noise. It was cool inside despite the horrible heat wave outside.
The space wasn't super-accurately presented by the photos – it was less well-organized, and we didn't see the coffee/tea/toaster, etc. There are some other things that are fairly quick fixes and would definitely make this space feel much more comfortable, safe, and reasonably-priced; I'll share these privately. What's harder to fix is the basement was really humid, to the extent that there was condensation on the floors, and towels hung up to dry were still wet 24 hours later. The weather outside probably didn't help, but a de-humidifier might be a good investment.
