Overall we had a very nice stay at C&M's place in OB. The room is small but it has its own little refrigerator and the bed is firm but comfortable. One amazing thing is that Charles let us borrow his bikes to ride around OB during our stay which was a very convenient way to see the town.
Great location very central in OB. The only thing you should be aware of is that there's a sky-light directly above the bed so the sun shines brightly in your eyes at 6:00am in the morning which makes it difficult to sleep in. If you're an early riser, it could be perfect for you. :)
