Radisson Blu Hotel, Paris-Boulogne

Room service delivered an excellent freshly made hamburger with fries in record time (20 min), but the chef's tiny, dressed green salad was unimaginative and mean.

1. Almost all rooms are noisy (street traffic and nearby arterial road) including rooms at either end of hotel, except Room.607. Double glazing is inadequate. A good night's sleep cannot be guaranteed. 2. The polite and helpful staff did not know where nearest letter box was. They checked Google and said it was at the entrance to the nearest Metro (600 metres away). And yet I found one immefiately outside hotel after enquiring. Some weekend staff seem to lack simple local knowledge.
