We were very pleasantly surprised about the hotel. Clean, friendly personnel, good breakfast, good location near a large shopping center. Easy access with buses. Very good hotel for the price we paid. No, nothing. We don't understand why some previous guests have complained. Complaints done by previous guests are not true.
Fairly basic, but good value for a capital city, if you know how to find it. If you didn't know how to get around Budapest using public transport, you'd spend a lot on taxis getting in and out of the city.
