I had a wonderful stay at Mercy's and Kevin's place. I stayed there for about four months. The apartment is super clean, modern, and cozy. Communication was efficient and any issues were resolved quickly. The place is close to grocery shops such as Whole Foods and Berkeley Bowl, but also to bus stops and BART, if you drive there is always a parking space nearby on the same street. The street is quiet and very safe.
Mercy and Kevin made my stay a home away from home! AND: their place is very close to Sweet Adeline - Berkeley's best bakery where you can grab breakfast or something sweet.
I recommend their place with all my heart!
