We stayed in this Zeus apartment in Palo Alto for more than two months. We had originally planned to stay longer but had to cancel early due to the Corona crisis.
First of all, the apartment is in super-great shape: large, bright rooms (two large bedrooms and one large living room with terrace), nice kitchen and two bathrooms (one with tub, one with shower), and very clean. The apartment came pre-stocked up with bathroom and kitchen amenities which lasted more than a month. The only small thing was that the heating is a bit noisy.
Second, Zeus was very professional in all interactions. For example, we called their 24h service number when we needed more towels, a new vacuum cleaner, or when the warm water boiler broke down, and they responded immediately by sending the new stuff and even had the boiler temporarily fixed and then replaced within a day or two.
Third, their and AirBnB's response to our early departure due to the Corona crisis was very helpful and professional. We had to leave early because Trump canceled all flights from Europa (and thus also the return flights). While AirBnB needed a while to respond (due to high demand), Zeus responded to our emails immediately and also proposed a voucher solution in case AirBnB would not refund our remaining days. Fortunately and courteously, AirBnB cam through.
In sum: a great experience in a great apartment in a great town, in good times as in bad times.
