Our ground floor apartment with a courtyard was lovely; really spacious, everything you need provided; scissors, cutlery etc.
Pros - easy access, nice furnishings, beautiful building. South Pigalle is lovely for food and shopping. Metro connections aren't bad, Saint Georges or Pigalle are just a few minutes walk away.
Cons - You can hear the rumble of the metro every few minutes. We saw no mention of this anywhere on the listing for this room - if you're a light sleeper, we would recommend going higher up in the building perhaps. We did get used to it, but it's constant until the metro closes for a few hours late at night.
There is zero housekeeping. You can ask for more coffee pods etc, but they are chargeable services. Which is fine if you are only away for a night or two, but we were there for 5 - so the bathroom needed cleaning, we had to buy toilet rolls etc., which isn't great; whatever your reason for being away, business or pleasure, you don't want to be worrying about supermarket trips as your time is valuable.
Definitely more 'Apartment' than 'Hotel', which we would usually recommend in Paris as Boulangerie breakfasts are typically better than Hotel offerings, but previous Aparthotels we have stayed in have offered housekeeping every 2-3 days.
The staff were friendly enough when we saw them.
Your money is paying for space, which is at a premium in Paris, not service. We hope this helps you make an informed booking!
