Six of us stayed at Riccardo's flat, and had the best time!
The flat is huge, and looks awesome, exactly as it is in photos.
The beds were all comfy and clean, and the rooms came with plenty of towels which was handy.
The location is great for exploring, and from a practical point of view is handy being near shops and public transport.
The only pointer is that if your English you may want to bring an electric travel kettle as we found lighting the gas cooker quite tricky.
I really recommend staying at this place.
