I recommend the corner junior suites
with panoramic views. Room 903.
Before ordering a room, ask about the set of services provided. You can enter the trading floor by attaching a residence card. Lately, it is not required to get to breakfast. The most convenient hotel was on the banks of the Danube park inn. Near the old town. I didn't stop after the restoration.
The hotel is very nice, wonderful breakfasts, located right under one roof with shops, including a large supermarket in the basement. I took off the star for the "incomprehensible" operation of the air conditioner (for 3 days of stay, I did not win) and for leaking water, I had to put a towel under the supposedly airtight door, otherwise I would flood the lower floors (I washed carefully))...
