In the last 3 years I've placed serveral orders with them - always delivered as promissed. I was even surprised once (in the positive way): they couldn't deliver as promissed due to the promo restrictions (from the hotel side), so they compensated at their cost - they just told me that they are doing it, so the number of nights was matching perfectly. Trust - 100% Delivery time 5/5 Thank you!
