Full House ApartHotel in Hanoi Center

The location on the map does not correspond to where the building is located! I booked an apartment for 3 nights, and when I arrived at the place on the map, I simply couldn’t find it. Tried to ask locals and taxi drivers about this address and they told me that this place is 5 km away. I also tried to call them on the phone number provided, but no one answered. The support team was also unable to contact after several hours. I booked another hotel in the Old Quarter and demanded a refund but they refused even for the 2 nights remaining. Please be careful about this place, looks like a scam for me.
