This is a fantastic Hostel. Staff were really helpful. The food was for Swiss standards was really good value. The location was perfect with good transport to the Hostel.
The best and most important feature for me was the Free use of all public transport, local busses,trains and mountain transport should you be staying 3 or more nights. This was just the best element of staying in St Moritz Hostel.
I would totally recommend this hostel to all comers. I stayed 3 nights and just loved it.
