Dear Sir,

Sorry if I answer you in english but I do not speak dutch.

Thank you for taking the time to review our hotel.

I'm glad you found your room nice and clean and the breakfast good.

I'm sorry about the noise made from the room close to your, unfortunately our rooms are not totally soundproof, and we trust always in the correct and respectful behavior of all our guests.
Anyway you could still communicate directly to the reception when you were here about this problem so we could ask your neighbors room to be more silent and respectful.

I don't know how you can say that your room was, in the past, forced with a screwdriver: since my parents have become owners of the hotel in the 60's we never had a theft and the tranquility and security of the area where the hotel is located has always been one of our strong point.
The signs on the door were caused by the intervention of a blacksmith, as a few years ago one of our customers has had an illness within the room and we had to intervene by forcing the lock and then replacing it. The door is perfectly safe and within the law, checked annually, fire-fighting and anti-panic opening.

It is true that we have four rooms with external access open 24 hours, but what you have not written, perhaps because you have not asked directly in hotel, is that: our reception close at midnight but the entire hotel is monitored 24 hours by security cameras connected directly with a 24-hour operations center; I live across the street and able to be contacted in case of emergencies simply dialing a number from the room.

Having said that, I think before you write such considerations (not real) about a property, it would be very important to make inquiries and seek explanations from the people who ensure your safety and giving you the service.
