Katerina was really friendly and very supportive. She sent us many recommendations of what to do in Prague and restaurants nearby. The apartment looks great and it was more than enough for us 4 people group. Location was also very good and close to metro station. Only remark is that the parking place is around 10min walking from the apartment. However, you won't use your car during the stay so it was totally worth it. I can totally recommend it. :)
