Booked 4 nights at this place, August 7 to 11. Some of the rooms smell sewage, most likely from the shower and some "Hungarian" construction. Checked in at room 5-1, had to change next day. At reception they asked if we had the windows open and ran the A/C on full, stupid question, you shouldn't have to do that to get rid of the smell. Over to room 5-3, same thing. Had to make a new complaint, and to my wife who's Hungarian, they told her to explain for me that it smells sewage in Budapest. Another stupid explanation. Yet another change and this time to room 2-4. Finally after two nights with sewage smell, we had a room without smell the last two nights, but packing up twice and move all things, spending two nights in sewage smell isn't exactly what you want for a long time in Budapest. I have since tried to get some kind of compensation for this, either a partial refund for the four nights we paid for, or two nights free if we come back there next time we're in Budapest, but still no acceptable feedback from them. Unfortunately Hungarian customer care at it's worst, which still seems to exist at this place.
Can't recommend this place, book something else.
