My family of 4—including an 18 month old and a 5-year old—had an excellent stay with no problems whatsoever. The apartment is convenient to multiple metro stations, not to mention the train stations. In addition, there are restaurants, markets, and bakeries within easy walking distance. In spite of the central location, the apartment itself is quiet thanks to the excellent windows. Inside, the apartment is quiet, cozy, and well appointed while having all the space you might need (3 bedrooms, a kitchen, and a living/dining area). Be forewarned, though: This apartment is someone's living space. This is quite lucky in my book because the space was beautiful, it felt like a home, and all the little details were attended to (for example, there were napkins and salt and pepper, which hasn't always been my experience with AirBnB rentals). But at the same time, for example, there weren't multiple empty closets of shelf space.
We had all the amenities that we might have wanted (e.g., washer/dryer, full kitchen, crib, wifi, toys, excellent shower, comfortable living space). But if you require something special, be sure to ask; Marie was very responsive and helpful. Thanks again for a wonderful stay, Marie!
