THE KEY ISSUES ARE: INFORMATION PROVIDED ON BOOKING.COM's SITE IS DECEIVING AND THE BOOKING PROCESS IS VERY TRICKY.
The first step I took was to book the hotel for one night and great that it offers free cancellation so that I have time to plan my trip. Then, I thought to myself that it is better to book one more night on the safe side so I changed the date to the 20th instead of 19th. After I received the confirmation email from Booking.com to my email, then I saw texts which clearly state that there is a cost to cancel the booking and "Changing the dates of your stay is not possible." I also read that the hotel is undergoing constructions works! Furthermore, under the Call-to-Action button "I'll reserve", the texts actually blink and I didn't see the words "confirmation is immediate".
