Le's place is pretty much exactly as described - very clean, and has pretty much everything you would need in terms of dishes/handheld appliances/necessities, and the shower is amazing. My friend and I didn't have as much time to explore the Capitol Hill neighborhood as we would have liked to, but from what we saw there were some great restaurants/bakeries/coffee shops within easy walking distance from the Airbnb.
We had some minor issues with check-in - the house was a bit difficult to find and we were given the wrong access code initially, but the hosts were very responsive and we were able to get in within a few minutes no problem.
The only other thing I would mention is that if you're leaving Seattle on an evening flight/redeye after checkout, be prepared to store your bags at a luggage storage place rather than at the apartment. We had inquired ahead of time about leaving the bags at the Airbnb until our evening flights and were told this was a possibility; however, that turned out not to be the case. Luckily we had friends staying nearby who offered to keep our bags for a few hours so we didn't have to go the luggage storage route - there didn't seem to be many storage facilities near the apartment that were open on weekends. The pitfalls of staying at an Airbnb rather than a hotel I guess :).
Overall I would recommend Le's place to people visiting Seattle.
