Will never go back. The hotel is relatively modern, clean, and the staff are polite. However, it is lacking in an absolutely essential part: it is terrible to sleep. The hotel has basically no sound insulation between rooms. You can hear every word, every step, every little movement your room neighbours do. I don't know how they managed, but sound seems to come out of every wall, like they were paper thin. In addition, the hotel seems to cater for party people, and Chinese tourists, both of which can be very loud. It was nearly impossible to sleep for three nights, even with ear plugs. Early night it was families with kids running around. Later on, was party people returning and chatting late into the night. Finally, from 5 am was Chinese people chatting (presumably jet-lagged?). It was an absolute hell, and I recommend everyone stay well away from Dormero Hotel Budapest.
