I have spent a month in Jons house and I enjoyed my stay!
Someone may say, that the house is far from the center of the city, but for me 30 min to the center is close enough. Otherwise the location is great: Walmart is nearby, Safeway is infron of the house, CVS pharmacy is next to the Safeway.
In my opinion Jon is a perfect host. For 30 days we did not have any problems/misunderstandibgs etc. And he gave me a few suggestions about where to go in the city, which were very accurate and userful for me (for example, I would defenetly miss the SECOND Air and Space museum without Jons help. And I also strongly recomend the second museum to visit).
I recomend this hous and this host for your travelling.
