We had a lovely stay at Ann's. The apartment was exactly as expected from pictures and accommodates 4 adults confortably for a long weekend. It was clean and had clean bed linens and towels. The location is great, I really enjoyed the opportunity to discover this area of Paris that I didn't know. It's also very conveniently located next to a couple of metro stations so easy to access from main train stations. It only takes 20 minutes from Gare du Nord.
The check in and check out went very well. Ann let us leave our luggage in the flat while we went to get breakfast on the last day.
I will go back without hesitation.
