My Girlfriend and I recently stayed at Nhu and Tom's place for 10 days and loved it!
The location provides easy access to lovely walks and beautiful views over the bay.
Nhu and her family were incredibly kind and accommodating, replying to messages speedily and even giving suggestions about where I could play Football during my stay.
The apartment was the perfect mixture of close to the city and yet felt secluded and close to nature, surrounded by trees, birds and squirrels.
I would absolutely recommend this apartment to anyone visiting Berkeley.
