I stayed at Zack place with a friend. Zack was very welcoming although we did not know how to contact him at the check in because the gate door had no buzz and we didn't have a US Simcard to call him. Everything was reasonably good for the price, like localization, neighbourhood, cleaningness. Zack and his roommate were nice and gave lots of suggestions on places to visit, transportation etc. Their cat Bob was adorable.
