Guillermo is awesome! I definitely felt very comfortable and safe staying in his 12-bedroom mansion right in downtown San Jose. Would definitely stay there again if I have to be up there for work. One thing to note is they are shared bathrooms, so if you really want your own, this might not be the best place for you. I made it work though, if the bathroom upstairs is occupied you can go to one of the two downstairs. Also, if you are lucky Guillermo might give you a tour of his lime plants and other plants he is working on! :)
