Executive summary: We would recommend this unit for short term stays, say, a week or so. However, in our experience, longer-term stays tend to expose Zeus's inability to coordinate with local crew to fix issues if things go wrong.
We (a family of four) booked this location, a unit within a 5-over-1 type of building, for a 6 month's stay recently. The unit has three floors, a bedroom and bathroom on the ground floor, another bathroom, kitchen and living room on the middle floor, and a second bedroom up at the top floor. Our experience was initially quite positive. The unit was clean (we were apparently the first people to move into this unit after the completion of the building), orderly, and the location is great. Just as advertised.
Initially, we had only a few minor gripes. 1) There was the annoyance of carrying groceries or heavy items up from the parking garage to the ground floor and from there to its eventual location in the kitchen, located on the middle floor (there is no service elevator in the building. There is a handicap elevator that runs up one floor at a glacial pace but whose use for carrying groceries is discouraged and whose keys are always missing anyway.) 2) Zeus reached out to us early on, mentioning that they needed to fix the Ring doorbell and asking for our permission to have maintenance crew enter the unit to fix it. So far so good. The issue is that despite several of these back-and-forth emails regarding the doorbell, nobody showed up. We don't happen to use these newer style doorbells anyway so that wasn't a big issue for us. But, we were a bit more concerned at the no-shows because it seemed to indicate a level of disconnect between Zeus and its 'ground crew'. More on this in another context below. 3) There seems to be some quirkiness in the electrical wiring of the unit because the circuit breaker for the living room area would trip spontaneously every several weeks. We were unsuccessful in trying to correlate this with the concurrent operation of any appliance or heating system.
Several months in, we were woken up one day at 5 in the morning by alarms that went off on every floor. As we did not smell any smoke or see any flames within our unit, we assumed at first that the problem lay elsewhere. A short time later we realized the alarms were specific to our unit. To silence the apparently spurious but still maddeningly piercing alarm we grabbed a stick and gently poked a spot on each smoke detector until its battery popped out (the ceilings are high and the unit did not come equipped with a ladder for us to reach the detectors directly.) Even then, there remained a kind of "chirping" of the alarm system, something we discovered we could only disable by manually flipping the circuit breaker off for the lowest floor. So, now we had silenced the alarms but had no power on the lowest floor.
Furthermore, during the process of disabling the smoke detectors we noticed water squirting out of the side of one of them. Apparently, water from heavy overnight rainfall had seeped in from the terrace on the top floor of the unit into the ceiling space of the living quarters directly below, shorting a smoke detector and tripping the alarm system. Because of the dual water-electrical nature of the problem, we sent out an urgent email to Zeus, explaining the situation. They sent someone out later that day to check things out, but this person did not appear to be a plumber or electrician specifically. I was able to explain the problem and show the resulting water damage on the ceiling.
Unfortunately, events from there on only reinforced our view of the seeming disconnect between Zeus, headquartered in San Francisco, and its local crews as I alluded to above. Despite a steady steam of check-ins on the problem, and promises of maintenance people that were supposed to come by, nobody actually did. Just establishing continuity in communication itself was a hurdle, with a different person answering emails on this topic every time at Zeus' end. After I pointed this out, Zeus made sure to have a single contact person from there on and offered to have us either 1) relocated temporarily to a hotel, or 2) another one of their units.
I think Zeus means well, but after 10 days of no power on the lower floor, the possible risks of a combined electrical-water problem and no-shows by maintenance people, we decided to move out of this unit well ahead of schedule.
