We spent with 5 adults five days in San Jose in Michael´s house, participating in a conference in the near-by conference center.
The house was perfectly located, so that we could go the 20 minutes to the conference center without using a taxi. We felt safe, but there are some homeless (and friendly) people on the way to downtown.
Around the house is plenty of space for parking a car.
The house is nicely decorated with 3 bedrooms and 2 bathrooms, ideally for groups of 5-6 persons. Michael´s reactions were always very quick.
The only issue might be the near-by airport, so that the noise in the early morning (as of 6 a.m.) is really disturbing, but we are anyway "early birds".
