Maria's flat is amazing! It is very close to the center and (that is my personal oppinion) very stylish! Our room was spacious, clean, full of light and we even had a separate door to the balcony. Unfortunately, we did not meet Maria but she was very nice in the messages. Her boyfriend was very helpful, kind, made us feel like at home. If we go to Zürich again, I would gladly return to them! :)
