Check In

We know many of you will come from Wednesday night to enjoy the iconic outdoor local milonga in the park pavilion at Grobovka, but most will arrive Thursday for the warm up milonga (1 block from the hotel).


Mosaic has a great restaurant that serves food in both the restaurant and the hotel bar. As the marathon day salons and the milongas are all close to the hotel, it will be super easy to come home, shower and rest in between, and enjoy the great food at Mosiac. See full menu here.

NOTE: Breakfast is not included in the price of your room unless you ordered it with the hotel. Breakfast buffet that will be available during the dancing breakfasts is available for 6 euro/person.
