When I arrived in Argentina at the hotel at noon (after a flight of 12 hours from Madrid), my room wasn't ready, so I was obliged to wait or walking on the street until my room was ready. I stayed for 2 nights. 2 weeks later I stayed another 2 nights in this hotel. I arrived from Ushuaia at 1.30h in the night. The reception-employee refused to let us in if we didn't give our creditcard (or 100$ in cash) as a guarantee for the mini-bar.
The rooms are spatious and clean, but for the wifi-network, they charge 25$ for 24 hours. Personally, I think that wifi should always be free.The location is ok, but not that special.
The hotel itself is a bit impersonal, but ok. The problem is with the service.

Duomi Plaza is a good hotel, I mean the rooms are very big and clean and the toillet is in the avareg. The people in front desk are very rude and unpolite and the location is quite bad although taxi in Buenos Aires are very cheap.
I had my voucher lost and the front desk woman was very unpolite to help me. She said that it was essential even though she looked in PC that was Ok.
I would recommend this hotel to cheap travel.

Me and my husband stayed in Duomi Plaza last year and it was great. Although the location is ugly it´s quite next to Corrientes avenue, Calle Florida, Puerto Madero and 9 July avenue. Very central place. The best of all was the huge comfortable room. Very friendly staff too. I recommend.

We really enjoyed our stay at Duomi Plaza. The location is not charming but very central and we could walk around all day long.
The apartments was very spacious with a brand new furniture, VERY confortable bed!
Breakfast could be better.
Staff tried to speak portuguese and were very helpfull.
