Peter's place is great!
My teenage daughter and I spent two nights there and were completely charmed by it. If you are lucky enough to stay there, you will definitely appreciate the warm, welcoming, stylishly decorated, very clean space, the comfortable beds with fluffy comforters, the great water pressure in the shower, the beautiful and very well stocked kitchen, the excellent tv/entertainment system with a big, cozy couch in front, the fireplace with a fluffy rug for lounging, and (if you are musically inclined) the awesome weighted-key keyboard & sound system in the living room.
Peter is a thoughtful, responsive host and his place a a real Capitol Hill gem within a short walk of a great variety of restaurants (both unique and chain style types) and shops (including a Rite Aid and an awesome grocery store (QFC - Thank you Peter for graciously providing a discount card for the store).
In case you are unfamiliar with the Capitol Hill area of Seattle, it might be helpful to know that Peter's place is a three story townhouse in a vibrant, high density, urban residential area. So just be prepared for walking up and down stairs inside his place and up and down hills outside of it. 😄 (So, probably a better place to stay with older kids than with itty bitty ones - your tweens/teenagers will think you're awesome for taking them to stay in such a hip urban place 😉).
Parking in Capitol Hill is always a challenge, but Peter makes it so much easier by providing you with a parking pass for on-street parking. Big tip: Parking on Federal Ave itself was usually full, but we always found spots available just two short blocks away (East) on 12th Ave. Also, I would definitely recommend having only one car with you - having a second car with your party would make things way more complicated for you.
I hope that's helpful to you - definitely stay at Peter's place - you'll love it too!
