Ben and Grace's place was great for a long term stay. I stayed for over a month and it was ideal since it had a kitchen, laundry, living room space with a TV, and easy parking. Ben was super friendly and easy to communicate with. The location was a bit further away from downtown but driving around was easy and the metro is only 15 min walk away. The bed was super comfy and the couch was nice to have!
A couple things to note about this location: it is a basement so you will hear the people walking above you occasionally. The people above me were always friendly and cognizant of the fact that I was living below them. It can sometimes get a little loud but it wasn't too bad. One other thing is that the laundry machines are shared with the folks above. Again, since they were so friendly, it wasn't a problem at all. I think Ben does a great job to vet out the folks who live above before booking them.
Overall, I'd definitely recommend this place whether you are looking for a short or long term stay! The hosts are easy going and very willing to share the space.
