Great people. They did a great job; let me check in early after a rough travel day.
Awful HVAC. The AC at this place - from the other reviews I should have read on this place - was very weak. It even broke during my stay during a heat wave (90*F/32*C).
Great Location. The hotel is right next to the U1, 2, and 3 lines which meant that everything in the city was easy to get to. It was also very easy to get to the hotel from the airport (S9, U1/3) and back (U2, RE8) IN about an hour.
Food is crazy expensive. The breakfast buffet (€15) really is pricey. The snack area is about a 3-fold mark up of the grocery store right across the street. Yes, convenience costs, but it was a little much for me.
In all, I would stay here again - perhaps not in summer and with a plan on getting snacks at the grocery store and not at the hotel. Lots of bakeries in the area and in the U station, head there for breakfast.
The people and location make this a great locale worthy to visit again.
