My stay at Ohkubo's place was ok, particularly given the great price and convenient location. The communication with Ohkubo was very easy and he was quick to respond and forthcoming, and check in was automatic and very easy and flexible to do. The apartment however is very old and smells uncomfortable when the air conditioning and the ventilators in the bathrooms are turned off. There are signs of mold or otherwise decay in the bathroom and shower, and some other furniture looks dirty (fridge, microwave oven), bed does not feel fresh. The pot in the kitchen was not clean with what looked like old food rests inside. An ok stay if on a tight budget, with a very welcoming host, but otherwise some aspects leave something to be desired.
