This is just one of the nicest places we have ever stayed, in so many ways. Many Bnbs tend toward the country/kitschy style, and are often overdecorated, which drives us crazy (we're an architect and an interior designer). This unit is furnished in high mid-century modern style, with classic pieces, some of which we'd never actually seen in person before. The furnishings, the art, the selection of art books on the shelves, the space, the light - all were fantastic.
At the same time, it was the best-appointed and most comfortable place we've ever stayed in. The radiant floor system in the living room worked incredibly well, and we were able to lower the temperature in the bedroom to just where we like it. There was a range of weights of blankets and comforters, and the bed and pillows were superb. We didn't cook any serious meals, but we could have with the fully-equipped and stocked kitchen. (The refrigerator was almost completely silent, which matters in a small place.). When we needed some little thing, we'd just look, and it was there.
The location and view were amazing. We were within easy walking distance to UW and the U District - a pleasant walk along the Burke Gilman Trail - so we didn't have to worry about finding parking near campus. The view was enthralling - the whole Eastlake side of Lake Union from the I-5 bridge to downtown, and then the Seattle skyline, visible from part of the living room and kitchen, and right in your face from the front porch/terrace. It really made hanging out enjoyable, being able to look up from reading and seeing that view.
Finally, the thoughtfulness of the hosts was extraordinary. They had left some lovely gifts, but we also had complete privacy. We did run into Alice by the cars one morning and had a lovely chat - about the place, where the furnishings and art came from, etc. Staying here was just the right balance of privacy and hospitality.
Overall, we couldn't have hoped for a better experience, and we certainly plan on staying here on any future trips to the city.
