The location is great - while in a quiet side street, the next bakery or cafe , restaurants and supermarkets are just very few steps away, and even to Sacre Coeur it is very close. Also just very few minutes to get to the next metro / bus station, also the hop-on hop-off buses are very close.
The Appartement is very nice, perfect also for a small family of 3 or 4 persons, the convertible sofa bed in the living room really easy to change to a comfortable double bed. We also liked very much the small balcony , where we could watch the shining / glittering Tourist Eiffel at night. Just be aware, this is a typical Paris building, so the balcony just holds a small table and 2 chairs ( which felt already luxury).
Yann is a great host and was very flexible about check-in /check- out details, and very nice to communicate with.
