It is listed as 5-star in booking.com. More importantly, when we get to the front office and asked why it's listed as 5-star, they told me it's what booking.com did. However, when we called booking.com, they told me the property defines themselves as 5-star. That's pretty confusing. Furthermore, when we booked on booking.com, it only charges daily rate, e.g. no rental or daily service charge. However, when we paid at their property, their invoice told us the rental and daily service charge are seperated.
But on booking.comthe listing clearly shows up as an apartment, not a hotel.
It also states in the property description that housekeeping is available 3 times a week, which is a pretty big indicator of it being a serviced apartment rather than a luxury hotel.
