The room was dirty and a total mess when we arrived. It took some time to arrange things and to get a new room, downgraded ie no penthouse view. With 3 kids and a lot of luggage it was something. The next morning we had to pack again to go back to our penthouse, but it wasn't clean, we already lost an evening and didn't want to lose more time, so we arranged something between the fridge and the reception.
Except of that we loved the MGM signature rooms, the people of this hostel were really helpfull and nice. MGM's suite are really perfect for family, we were 2 adults and 2 kids with a baby, and we had enough space. Kitchen has a nice furniture, I'll definitly recommand this hostel for family. But maybe next time we'll go directly with the standard management.
