We loved our stay at the apartment at Gästehaus Rosenhof. All the staff were very friendly and helpful. The apartment is well equipped and comfortable and worked well as a base for a family of 4.
As we were travelling by train, the location couldn't be better, being just 2 minutes from the station. The centre of Mayrhofen is only a little further away.
Only minor issue was that Hotels.com advertised free breakfast as being available when booking the apartment, but this is not the case. It is only when you book one of the standard rooms, but I believe this is not the fault of the hotel.
Mayrhofen is a great base to explore from and when we return, which we will, we will be looking to stay at Gästehaus Rosenhof again.
