HRS is a hotel booking website similar to Ctrip and agoda. It is just a German company and has been established for more than 40 years. When I went on a business trip to Europe last year, many colleagues in the company were using HRS. They told me that HRS is the largest hotel reservation website in Europe, which can be said to be the "European Ctrip". Then I used it myself and got a feel for it, and found that there are indeed many hotels on HRS, including Paris, London, and Berlin. Moreover, what I find particularly cool about HRS is that it does not require credit card guarantees or prepayments. When traveling on a business trip, the most annoying thing about guarantee payment is that once the itinerary changes, it will be troublesome. You can check in after making a reservation at HRS, and you can settle the bill after your stay. The hotels booked through HRS have a good environment and are high-end, which is quite reliable. However, now that HRS is our company's supplier, I rarely use HRS to make direct reservations. However, my family often makes reservations, and they have never complained about any hotel reservation problems. The hotel photos taken while out and about are also very good! Anyway. HRS is quite worry-free, just try it yourself and you will know.
