Whenever we're in Bacharach we stay at Pension Lettie. Lettie is nice and friendly. She always has lots of info on the area. The prices are great, great breakfast. This year, I tried to make a reservation but couldn't get through. Turns out she's having problems with her email. I had to make the reservation by phone. If you are having trouble contacting her by email try this one: firstname.lastname@example.org
That is too bad that she is having email problems. We stayed with her in the past. It was a great place and Lettie is very helpful.
If there are problems in the future, you can always contact the Bacharach Tourist Office. They have been very helpful in contacting my desired Zimmer which doesn't have email.
