Book Frederick's flat! The view alone is worth the booking. And the metro is at the foot of the building. Though it's farther away, it's actually worth the extra transfer as you cannot beat the view of the Eiffel Tower at night. Plus the metro is very easy to use. Probably the easiest underground to get around as a foreigner so it's not a big deal to be farther away. Plus it's quit crowded by all the attractions and the quiet was nice. Just be aware of the Sat night crowd at the cafe across from the flat. But if you like to drink, that might actually work out for you. Also the Italian restaurant across the street is fantastic. Very good service to foreigners and the food is authentic Italian. If I was a newlywed, I would stay here. You can save on hotel fees and spend that money on a great meal.
