Helen double booked us and handled the situation terribly. Helen tried to manipulate the situation by offering us an "upgrade" at a lodge that "wasnt in operation or online as they only accept repeat guests" and telling us if we didn't accept the alternative accom air bnb "might offer us some compensation".
Being just ovet a week out of a 5 month planned trip we Decided to trust Helen and the reviews online about her and accepted the new accom.
On arrival we realised it was a guest bedroom in her family home with no privacy, not self contained and nothing like the original Tamar Rydge valley. After politely expressing our disappointment we asked if any of the original acom were free on our dates. Helen said 3 of the 5 nights at the orginal place were free. We accepted, said thanks and that we would rather stay elsewhere for the first 2 nights and not in her house as we preferred privacy.
Helen then got aggressive and started yelling about how we "mucked her around" and that we couldn't stay anywhere, told us to leave and refunded our entire trip, not letting us stay at the original accommodation at all.
We were left stranded struggling to find accom with only one night of accommodation booked for our 5 night stay in Tassy. Very stressful and very unprofessional and manipulative from Helen. If she ever offers you accom at "Grindlewald Lodge" - check it's not a room in her house!
