Extra costs were demanded without receipt. Include in the payment from start and we will not have to pay you "black money". We were in Milano to have a romantic weekend and were interrupted on and on with discussions about extra costs. Also, it should not be a problem to put a forgotten thin pillowcase together with the receipt in an envelope an send back to us. As our flight was late, we were first met with "this is a huge problem for us"-attitude, then it was ok, but we had to wait for the key even though communicating exact arrival. Host was late also by departure and we had to run to catch our return flight. Due to this, we cannot recommand this.
