We had a wonderful stay in Vienna in Petre's apartment. It is very well located, perfectly equipped, clean and comfortable. I would stay there again without the slightest hesitation and recommend it highly. Petre responds extremely quickly to any need a guest might have. The heating was not functioning properly at the beginning of our stay, and when we still could not get it to work after a couple of messages back and forth, Petre even offered to come to the apartment immediately although it was almost 10 o'clock at night. He fixed it all quickly and efficiently.
