Wow what a great little place in the Capitol Hill neighborhood! Close to so, so, so much things. Just a few blocks South and anywhere West is about a bajillion food/bar/restaurant options. We found the Jimi Hendrix statue that is a 4 block West and 1 block South walk. A nice fairly easy walk from the Capitol Hill light rail station (0.5 Mi away). You can short cut through the park, but my two friends had roller suitcases so we had to stick to sidewalks. Howard appeared to be ever so slightly less of an incline than E Olive if you're hiking from that direction.
As a three time Seattle vacationer, I did appreciate the coffee table had an array of pamphlets for various downtown attractions; MoPop, Pikes Place Market, Glass Museum, etc...
The room sizes were very nice, the master bedroom being much larger than I expected and it had a closet, too. The bathroom and kitchen are nice and modern. Everything anywhere in the unit worked flawlessly; taps, sockets, light switches, etc... None of us encountered any problems with anything at for our stay. It is true that it is right beside a parking lot, but we just kept the blinds down for the most part so that wasn't an issue at all, really. As we were walking up to the place on the first day, we met the caretaker of the unit. Very friendly guy and he advised us the city had been doing some water main construction in the area so the taps may run a bit yellow/hazy. But, again, never had any issues that I could see. We tested all the taps and they all ran clear. Our trip was in mid May, temperatures stayed fairly warm and on and off clouds at different parts of the day. I noticed there was a temperature control in almost every room; living room, bathroom and the master bedroom. So I guess each room gets it's own small heater or something. Never had to use it for our trip, it was warm enough on it's own from outside. Ah, the unit above sometimes you can hear when the toilet flushes through the connected drains, but that was about it for noise we could really hear from above.
Ah, I never rent a car or anything for my vacations that I fly too, can't be bothered, seeing as I drive for work and when I'm on vacation I want to relax. So I cannot comment on any sort of parking tips or issues for the area.
Just, a really great deal for such a nice place and "home base" for any sort of adventures or vacations in downtown Seattle!
