The space that Maija offered was great! Just enough space to have 2 people. Not exactly sure about 4. Although there are a couple things that people should know beforehand.
1. The house is a little difficult to find / get to.
2. There were no bottles of water or water filter, if you're OK with tap water that isn't a problem.
Other than that, the stay was amazing. Definitely a great location to have your stay in Seattle.
