Although we have received a confirmation of the booking, there were no rooms for us. The hotel had booked us into another appartment - out of the centre, 2 classes below the one we booked originally. And they charged on my card original price 436 eur while the real price of the appartment was 290 eur!!!!! After very hot conversation I was promised refunding of the excessive amount plus discount 13 eur for the taxi to the city centrer. This practice becomes very common in Reykjavik. Services in Iceland are somewhere on level of 20 years ago in Central Europe.
