This apartment is in a great location - not far from Montmartre and Pigalle, close to metro stations and bus, walking distance from Gare du Nord, close to beautiful Rue de Martyrs and Opéra, with heaps of top-quality bakeries, shops and restaurants nearby. There are bars around which means it can get a bit loud at night but I managed to sleep well anyway (and I'm a light sleeper). I was travelling solo as a woman and I found the area pretty safe.
The apartment has a nice bohemian character to it, the bed is really really comfortable, there’s a desk for remote work and a fast and stable internet connection. The view is lovely. The people managing the property were always quick to respond, check-in was smooth and easy. I changed the time of check-in at the last minute and they had no issue accommodating my plans. I asked for some laundry detergent and they had it delivered to me within a few hours, really no problem there.
However, I found the apartment to be a bit dusty. I washed every mug, plate, cutlery and pan before use because they had stains/didn’t look well cleaned. It’s quite old, which adds to the charm but also means creaky floorboards (from upstairs too). The TV is old, would be nice to upgrade it - I’m sure it’s not a problem for people who stay for a holiday but I stayed two weeks and was working during the day, so I wouldn’t have minded being able to watch some Netflix at night. The hairdryer is really tiny so if you have very long hair like me it will take you a while to dry it.
All in all it’s a good place to stay if you’re just in Paris for a holiday but I wouldn't recommend it for longer stays.
