We got back yesterday afternoon after 4 nights in this superbly located hotel and can't wait to book again.
Literally just over the Seine, across Pont Citie, on Rue Saint Michel, our room overlooked the river and Notre Dame.
The Hotel doesn't look much from the outside, but the minute you walk into reception and meet the staff the place is first class. We were on the 4th floor, only 3 rooms up there) and the room was plenty large enough, the bed huge and comfortable; a very decent bathroom, shower etc and WiFi is free (tell them how many devices and you get that many logins)
The room, with the window open was noisy, it is situated on a busy road, but with the windows closed at night, together with the air-conditioning, made for a very peaceful sleep.
We had breakfast in the hotel the first morning, European breakfast, 15 Euros, for all you can eat; fresh juice, coffee, tea, eggs, meat, croissants with jam etc. The next 4 mornings we had a cooked breakfast at a local cafe.
Each room has a mini-fridge, which is where you will find the small safe (again gratis) for your passports etc (not bit enough for my iPad, but you could leave that with the staff when you went out)
In the heart of the Italian Quarter, there are so many restaurants and bars of all prices (cheap to first class)
Only gripe, just the 2 small cartons of milk, so you could have just the one cup of coffee or tea using the kettle in the room - but I'm sure if we'd asked, we could have got more.
Absolutely highly recommended.
