We stayed in Prague for 4 days and were very happy with our stay at Daniela's place. The appartment is exactly as described and contains everything you need, including a small fridge, microwave, kettle and - what I liked most - a vinyl record player ;). The flat is located next to the castle, meaning that the area is full of tourists during the day (reflected in restaurant prices nearby) but very quite during the night. You can reach all major sights by walking.
Daniela was on holiday during our stay - still everything worked out just fine and we were in touch regularly. We can definitely recommend staying at her place!
