This apartment is great! I had a very nice time in Paris and this apartment had a big part of it. It is small but it has everything you need. For a short stay it's not a problem. The kitchen is fully equipped so you can cook your own dinners. Getting the keys is easy, I arrived at midnight and had no problems getting in. Oh and the view! I loved those rooftops, the Sacre Soeur and that French flag across the street.

About the neighbourhood. Yes, it is not the nicest. It' dirty, smelly and crowded during the day but they clean it up (to some extent) in the evening, the crowds dissapear and it gets quiet. It's definitely not dangerous. People just mind their own bussiness there.
