We booked an appartment on Chalet Plus, but they raise a bit unusual conditions. They ask the whole booking fee till december, but they will send the voucher only in February. They are also not willing to give any contact to the apartment, although we have already payed a part of the fee.
Though their webpage seems quite professional, I'm a bit worried. So if you have ever booked an accomodation on their site, or you know them, please let me know your experiences. thanks a lot!
