Practical Informations
It is best not to go through sites like booking.com, taking up to 50% commission on your reservation. In addition, this site will not guarantee your reservation. Some customers have already noticed, once they got to the hotel, that their reservation didn’t exist. So you end up in a hotel that you did not booked (the hotel can be better or worse!). Send an email directly to the hotel concerned!
Here are some links to sites that can simplify your life and give you good ideas to travel:
