Ahmed's place is nice, cosy and clean. We liked the location - 4 mins by foot from a U1 metro station. Communication with Ahmed was easy, smooth and fast. During our stay it was really cold in the city so we recommend keeping the heating on. It smelled of gas because of the heating but it was't too unplesant. The place is close to supermarkets and has kitchen appliances so you can cook for yourself. There is wifi but we didn't really test it. The bed is comfortable and there is a sofa for additional peole - up to 4. It's perfect for staying in Vienna, close to the city centre for a reasonable price.
