Stay here! This wonderful flat is spotless and even nicer than the online photos, with a little patio area out front for sunny morning breakfasts. The inside is bright, open, and extremely comfortable with a couch, TV, and Roku for evenings in. This flat has everything you could possibly need -- a giant closet with wine crate storage, a fully-stocked kitchen, a washer/dryer, a wonderful neighborhood (my daughter highly recommends the Cereal Pancakes at Glen Park Cafe on Chenery and Diamond), and free street parking. A space heater and towel warmer were also available, although we didn't need them.
There is a BART station at the bottom of the hill, and the Muni tram stop is just to the south of BART. The tram stop can be hard to find, so go south past the BART station on Diamond and there will be a walkway down to the San Jose/Glen Park Muni stop. It is a short 5-minute trip up the hill on bus 52 from the BART station if you are tired of walking in the evenings.
For truly noise-sensitive people, this is a downstairs flat so you can (very) occasionally hear someone walking upstairs and you can hear the heating kick in. However, this is a very quiet location with zero street noise in a huge city. Adam's place is quieter than any flat I've ever lived in. Heck, it is quieter than most high-end hotels I've stayed in.
Overall, our experience was amazing. Adam helped us extend our stay after our travel plans changed. When we left a backpack sitting on the sidewalk one morning, he went outside to look for it after we discovered it was missing when we got to Muir Woods. The neighborhood is so nice my pack was still there an hour later!!
