The overall stay at Hotel San Pedro was absolutely amazing.
The receptionist was very gentle, and the room was very clean without any bedbug.
The location of the hotel is very good, as you can almost directly go to the shore as well as Grand Be when it is low tide.
After checking out, the receptionist allowed me to leave my baggage till the afternoon at the lobby so that I can pick my baggage when finally leaving Saint-Malo.
I would definitely stay again at Hotel San Pedro if I revisit Saint-Malo later.
