This was very convenient for me while I attended a very intense conference at SAP Center. It's about a 20 minute walk, no big deal for a New Yorker, and I used Lyft to get there for the morning sessions - $7 + tip - and walked home, sometimes after midnight, without any concerns (please note, I am a long time New Yorker - if you are not comfortable doing this, take a Lyft or Uber - it's less than $10 one way).
The bedroom is large. It's a very comfortable bed. It was cold, but became comfortable after the heater was left on for a while. I didn't eat much in the house but there is a kitchen with a refrigerator and a microwave, and plenty of utensils to use.
I only met John once (check-in) because our schedules didn't coincide, but he was very friendly, provided lots of bottled water for me (I requested no food be provided, but he still made community fruit available), gave me an extra pillow when I requested it, and invited me to make myself at home.
The house was very quiet, which I was thankful for because I was coming home late, sleeping and then heading back out around 7AM. It was a good value for someone who needed somewhere to crash.
