Loiuse's apartment is just perfect for a city break. The location is superb, right in the heart of Le Marais, and we walked everywhere from the door. Her tips on where to eat in Marais are excellent: do try L'As du Falafel which is busy, bustling and has enormous portions that are very tasty; also, we went to Robert et Louise grill/steak place and can vouch for its 5-star Google reviews.
The apartment is spotless and the bathroom hotel standard with no issues about hot water, towels, soap, etc. The beds are comfy and there is plenty of wardrobe space. We appreciated having two separate bedrooms as we traveled with our teen son. Usually, and especially in Le Marais area, you find a sofa bed for the third person. We didn't miss having a sofa/ couch as were out all the time really so the extra bedroom was more important for us.
The building is an old (medieval?) one nicely done up - the landing and communal spaces have just been renovated. It's quaint finding the flat door actually off the spiral stairs mid way between two floors. The place is also very quiet.
Louise was so responsive and helpful with taxi info and on hand immediately on sms for anything we asked. Self check in much appreciated and easy, as we arrived late and left crack of dawn.
I can't recommend Louise's apartment highly enough and we will certainly stay there again on our next trip to Paris, both leisure and business, as it was this time.
