Trevor's suite is very spacious and large enough to accommodate two. It is clean and well furnished. The private bathroom is large and has a full size bad tube.
My girlfriend and I stayed at Trevor's place for three months. I worked in downtown Berkeley, easily reachable by bike. Trevor allowed me to use his extra bike! A couple of times I used his well equipped main kitchen. Most of the time I only needed the fridge and microwave in the suite. Trevor is a very friendly guy and a great host. He was very helpful and also picked me up at the nearest BART station when I arrived. Furthermore, you have a lot of privacy if you need. You have your own entrance and complete freedom when to come and leave. The suite is almost like a private apartment.
I would definitely stay there again.
