The lakeside apartment is an incredible spot!
The interior is spacious with a living area, bedroom, and kitchenette area, and has great spots for both relaxing and working. The back deck is connected directly to the space and is huge with a table and chairs, and hammock. It's worth booking here for the views alone. You have Lake Washington and Mount Rainier both visible.
The location can't be beat. It's less than a five minute walk to a trail that runs along Lake Washington, and opens up to Madrona Park, which has nice spots for sitting out, and a beach for swimming. I think I took advantage of this every day of my stay.
There are also two pockets of restaurants and shops within a short walking distance - the Leschi Marina area, and Downtown Madrona are both worth checking out.
Rao and his wife Xingchun were also very accommodating. They checked in by text periodically to see if I needed anything, and we even had tea together to close out my month-long trip. Was a great time!
Would highly recommend!
