The place: The apartment was very clean and orderly. All of the basic cleaning and cooking materials were provided for us, which made getting settled a lot less of a hassle. The apartment has every that you would need: kitchen, washer, dryer, hairdryer, etc. It's also close to all of the restaurants in Russian Hill, which is nice because you don't have to Uber to get a decent meal. For the purpose of our trip, which was to work, it was kind of close enough to the Fidi/Embarcadero Area. 20 min walk gets you to Embarcadero and 15 mins gets you to FiDi. Very quiet and safe neighborhood with minimal disturbances. There's also a dry cleaner down the hill that also takes UPS packages, which was very convenient.
The host: Great host. Kenji waited to greet us at our apartment when we first arrived. He was very patient in pointing us to all the attractions and restaurants. He is very responsive and helpful with anything that we needed. The biggest thing for me was how he was willing to help me move my delivered packages inside the apartment so that they are secure when I get back from work. He also brought us brownies and wine. Really nice and cheerful guy overall.
Overall, pretty satisfied. Great location/neighborhood and great host. Would recommend for larger groups of people who are planning to stay 1 month+.
