The hosts that I met, Ed, and one of the staff, Phil, were both very gracious and helpful.
Electronic locks for front door, guest rooms & luggage storage - very convenient (I booked late and arrived in the middle of the night).
There is an outdoor patio & grill with large patio benches, so it's a great place to chill with the weather being pretty nice in the evenings.
As the host warns on the site:
1) It IS noisy (you're right at the corner of A & 7th) but I always have earplugs with me so not a big deal.
2) It's cheaper/safer/easier to take Lyft or Uber than to rent a car, if you're going anywhere within 10-15 miles of the area. Links to free first rides (up to a certain amount I think):
Lyft: https://lyft.com/iga/JDTUTKRKMDXFVJ4C
or
Uber: https://www.uber.com/invite/mye167ue (up to $5)
I used primarily a Shared Lyft, and my rides were discounted down to ~$3 (from between $7 and more).
If you're driving a car, parking during the day is metered (every 2 hours or something like that). Parking at night is free & very easy. Both nights, I was able to park right in front. You have to move your car or put money in the meter by 8am.
It's not a private house or condo - I think it was a hotel (Chadwick?) so there are quite a few rooms next to each other, a few stories high.
