Anne & Girts were incredibly hospitable when I stayed with them, and the MIL apartment is very nice. It has enough space for several people, and a full kitchen, which was a big plus. It's nestled in a residential area, but the 26 bus stops right at the top of the street, so getting into downtown was easy. Greenlake itself and grocery stores / restaurants were about a 15 minute walk away. Fast internet and laundry in the bathroom as well, really had everything I needed, and then some.
As hosts, Anne and Girts were super welcoming, staying in contact through text, or just going upstairs and knocking. They went out of their way to help me out a few times, and are just great people. Their dog, Peanut, is friendly and cute as well. I'll absolutely be recommending staying here to anyone I know who visits the area.
