Are there bathrobes for guests in each category of rooms?
Our Superior room had robes and we have stayed in the Deluxe where they are also included.
Yes there are. Nice hotel. Make friends with people at desk!
Our room was not a 'superior' one but bathrobes were supplied. I guess all the rooms have them. It's that sort of hotel.
If you're coming to Budapest these days, it's very hot and sultry!
Robes were provided in the double deluxe room that we booked. I assume the same for the other categories. An email to their reservations or customer service would be the best way to confirm.
