Wonderful spot, we would definitely return if going back to Seattle. First time visitors to Seattle and only had Google to go off for neighborhoods and we actually fell in love with Capitol Hill! It felt safe, the houses/neighborhoods were charming, and theres a lovely coffee spot just a 4 min walk away. This place is really close to the UW Arboreteum, a 12-15min Uber/drive into downtown (pike place Market, art museum, etc) - I couldn't have been happier picking this spot. We rented a car last 2 nights and had 0 problems finding parking.
The place was clean, roomy with 2 bedrooms (living room separating them), clean bathroom, kitchen, washer/dryer was so nice to have. It is in the basement with a private side entrance, you will feel a bit pressured to be quiet at night with your voice or closing doors (as opposed to occupying an entire house yourself), and you can hear foot steps and movement from above. It's nothing outrageous and wasn't a problem for us, but it is worth considering if traveling with people who would mind or who you feel would be disruptive to those above and cause stress. The hosts were great, easy check in and out instructions, checked in with us during our stay, and were quick to respond for any questions. We didn't need much as the place had it all, though!
