Good afternoon, my experience, unlike some of the reviews I've read, has been quite good. I received a call from a friend, and since I had a trip planned, I decided to buy the offer. The very next day I called to make the reservation, and not only were they very kind, but they also adjusted my booking in Madrid as I requested. So from my side, I recommend the service. I've already saved money just with that reservation. I hope this helps and encourages you to give it a try. Best regards.
