Marine was very communicative and transparent about the apartment before I even booked the unit. It can be warm in the summer, and the apartment is a 5 story walkup - 6 if you count the apartment's second floor. Since there were two of us arriving at 2 separate times, Marine was very accommodating with our disjointed arrival schedule, as well as with checkout which was all unnecessary, but very nice. So unexpected, but we're so thankful as well.
This apartment is in the ideal location, between Le Marais and La Bastille. Many restaurants and shopping options at each end of the street. And close to 2 metro stations.
We were there as the cool weather was settling in, so it wasn't warm on the upper floors. There's plenty of room for 2 people, but it could easily accommodate 4 if necessary. If you've never been to France before, you must be aware that in most older buildings, the toilet and the shower are in two separate rooms (on two separate floors in this two story unit). I wasn't bothered by this, and found it pretty convenient if both needed to be used simultaneously, vs traditional bathrooms.
Although we spent most of the days touring around, it was nice have a place to retreat with a kitchen, space to work, washer/dryer, bed, couch, etc - all the comforts of home.
Honestly, what can I say that everyone else hasn't already said - this is a great apartment and I'd definitely stay here again on a repeat visit.
