We ordered a 30m2 studio with privat bathroom, and announced more than 1 week before arrival, that we would bring our dog which Bettina cornfirmed was OK for an extra charge of 10Euro.
On arrival, we got a room half the size, no bathroom, toilet in the corridor next to the entrance and noisy teenagers from the owners private quarters on 1´st floor 2;30 in the morning.
A discount of 10 Euro was provided, seeing no other option we had to take it.
The 2 beds consisted of one bunk bed and one sofa with plastic under the synthetic bedclothes, not very pleasant with high night temperatures and no aircon.
This has to be compared to a stay at the Steigenberger in Lörrach on the same trip, where we for the same cost (incl. dog) got a very modern and spacious room at the 14´th floor with a spectacular view and with breakfast for 2 included,- a service for which Bettina would charge 24 Euro extra.
