We stayed at Karina's studio for one week during Christmas time. The house is spacious, well equipped and has the best location you could ever ask for: walking distance to Union Sq, AT&T park... and multiple bus stops are just steps away. It is very quiet at night so be sure to keep your volume down. We celebrated a bit too much during our stay but Karina was very understanding. She even gave us a lovely gift basket for the holiday. I would wholeheartedly recommend this place.
