Katia is pretty nice and patient to answer all my question. She gave me great suggest. Even though I didn't meet her, we got in the flat easily and had a wonderful trip. The flat is located in an extremely great place, near to the Nobel museum. There are many great restaurant around it! We didn't take any bus or cab while staying in the city, we walked to everywhere (at most 30 min walk). We have 3 people, and I think the flat is big enough and really comfortable, design simply and look great. I would absolutely recommend this flat!!
