Terrible! When you arrive, you will find a closed door with a paper stating that you have to call to a phone to request to enter, so you need to have roaming or a local sim card. I called 6 times during 30min, at the end, I started to look for another hostel and when I found another one then Castle Inn people called me. I went back to that hostel and the guy requested me to wait because he was needing to find my booking, I waited at least 15 minutes and then another employee from the hostel, who was sleeping in a room got off from that room and told me this is your room you can enter. When I got in the room I found: blankets had spots, the toilet was dirty, the TV didn't work, the pillows were having spots... I don't know spots of what but for sure I didn't want to use them they were not clean for sure.. It was terrible but the service was already charged to my credit card. Another terrible thing is that Hotels.com, after I booked the hostel sent an email staying that for contacting the hostel I can call to a.... they didn't put any number, when I called Hotels.com they gave a number of the hostel. When I used that number to call the hostel, the number didn't exist; hence, what can I say about Hotels.com, seems they don't check whether the information is updated or correct regarding the hotels they offer in their webpage. Overall, totally disappointed of hotels.com because when I called them It took me also like 6 times to get a reply and at the end gave me wrong information.
