I was visiting Mountain View for 3 weeks and chose to stay at Carol's apartment. I cannot recommend her place highly enough. It is perfectly located, a short walk to downtown MV, on a quiet street in a residential neighborhood.
The apartment itself is huge, 2 bedrooms with a lovely small balcony/patio. The bathroom and kitchen both are very clean, and stocked with essentials. The living room is large and comfortable, the bedroom and closets have plenty of space for this space to feel like your home away from home, especially if (like me) you have a longer stay.
Carol and Mickey are responsive hosts, who take their responsibilities very seriously. We communicated back and forth several times in my first few days about a few minor teething issues.
I have absolutely no doubt that I will stay with Carol in this or one of her other apartments during future visits. If this place meets your needs (size, price, etc) it's a no brainer.
