The Leo, the hotels roof top bar is stunning. Great open air balconies with sweeping views down the Danube river, parliament building etc as well as behind the hotel where you will see Fisherman’s Bastian, royal palace etc.
Service is friendly (by Hungarian standards, as not known for their service) and professional.
Hotel Building is stunning, very luxurious, modern and decadent . With a cosmopolitan vibe. The rooms are compact but well appointed and highlight would be the walk-in rain shower, excellent large comfortable bed and espresso maker (with proper glass walled cups etc)
Negatives would be the size of a standard room, the opening of the shower/wc doors is essentially into the bedroom area. It’s a unique setup and not seen in other 5* hotels I have stayed in before.
