Due to Helder Opera hotel overbooked, I did not have a chance to stay in that hotel. Instead, Helder Opera moved me to another hotel (Hotel London), which next to them (3 mins walk). I enjoy the same rate + "free breakfast" ~ I am happy with that. The lady in Helder Opera (I do not know her name) speaks very good english. She is very nice and helpful.
The location is very good, just 5 mins walk to Galeries Lafayette Department Store, very close to Roissy bus stop.
In hotels.com, I have to click everything in their survey in order for me to post the review. Why?
