I've stayed by Chris for a pretty long period (approx. 11 days) Chris has been a great host, very helpful, always very friendly and available for a chat.
The room is comfortable, with a private bathroom attach right to it. Besides the room, also the rest of the apartment is very nice with a very large TV room, kitchen.
The position is really great. It is a 10 mins walk to the Caltrain, and to S. Clara campus. In addition a number of shops are at walking distance. The district is very quiet, a little close to the railway, but not too many trains and stopping quite early at night.
All in all, a very pleasant stay. I definitely recommend Chris room to anyone staying in the valley.
