Another point you may not have thought about, is that in Europe it is rare to get facilities for making a cup of tea or coffee in your room, so do not be disappointed if you do not have a kettle, etc, but the hotels that do provide this service usually make a point of saying so. Also, most hotels in Paris do not quote a price with breakfast included as this is usually an optional extra charged per person, but some basic hotels and one star hotels do not serve any breakfast.
