Christine is really nice and welcoming and she will definitely be willing to answer questions, resolve issues, and help you out. The location is really special--a beautiful, safe neighborhood, parks and lakes in biking distance, and a smattering of folksy cafes and shops.
For a long-term stay, you should really be booking a place with security and privacy, but this is perfect for stays of up to a week.
Regarding security, none of the doors in this building lock. There are some pretty obvious concerns--for example, the bathroom door, which does not lock, regularly swung open while I was showering. My bedroom door likewise did not lock. And by the end of my stay, I noticed that the house's upstairs security keypad beeped and made noises but did not actually lock the door. The front door is unlocked at virtually all times. On most days, then, there is not actually anything preventing anyone from entering the building and then entering any room they desire. This is a safe area in my experience, but if you're looking for an actually secure location, or are traveling with anything valuable, this is not a place you should stay. There is no way to prevent other guests from entering your room. For all these reasons there is very little privacy as well. Again, this is the kind of concern that wouldn't be a big deal for a brief stay, but is worrisome for a long-term stay.
The other thing I would mention for a long-term stay is that the oven and stove were pretty scattershot in terms of function and overall cleanliness, and since you're sharing the fridge with as many as three other people, you don't have a lot of space for groceries.
Another thing is that there were a lot of issues with the WiFi, which was regularly (on a daily basis) so slow I had to switch to data. So be cautious if you plan to get work done online here or if your data plan is limited.
Finally, make sure to double-check on your lodging and amenities. The room I booked had a desk, and the listing did (and still does) include a workout space and treadmill. The room I was actually placed in did not have a desk or space for a desk, and the workout space has been converted into lodging. So--and really this is just good AirBnB practice--you should be sure to double-check with the host that everything mentioned in the listing remains accurate and up-to-date.
So again, overall, the host is wonderful, the location is close to ideal, but security and privacy are real concerns--good for a brief stay, functional but not ideal for more than a week or so.
