Our family of four had a great time at Gerrit's apartment, which is clean, centrally located and has everything you need. Self check-in is fast and simple (no matter when you are arriving) and communication with Gerrit is super fast, as he responds almost in real time. Neighbourhood is quiet, supermarket is around the corner, metro station is 2-3 min walking distance, and our kids (4 yr old twins) loved the apartment. We would recommend it to anyone who wants comfortable stay in Vienna.
