Christophe's apartment is located in a great location within walking distance or a short public transportation drive to all the main sights of Vienna. This is a regular neighborhood and therefore we saw fewer tourists in the streets, which is a virtue for us. The apartment itself was wonderful. Equipped with everything you need. Easily accommodates four adults (or in our case two adults and two children). The building is comfortable and charming, there is a lift that works and is the apartment has no street noise. Christophe himself was an exemplary host. Although we did not meet for various reasons, he made sure that the apartment's cleaning lady welcomed us (it is important to note that it was also at a very unconventional time - midnight). She opened the apartment and he called to describe it. During the nine days we stayed in the apartment we were in contact several times as well as before leaving. In short, a personal and caring relationship. Just what one looks for. Our children did not want to leave. We'd love to come again.
