The location of this apartment is excellent, very close to a couple of metro stations. My colleagues and I work together in Paris twice a year and we really like this neighborhood as it is full of fun and cool bars and restaurants.
Adrian was very quick to answer my emails and the apartment was clean and had most things needed.
I do however have a couple of grumbles. We were a group of five and we were only given one set of keys and then had to pay to have another set delivered. I think when you are letting an apartment for up to six guests you should ask how many guests will be staying and offer another set of keys.
Additionally regarding sleeping arrangements, if the sofa bed had already been made up, that would have been nice.
Lastly being met by a concierge is not something I have ever experienced through air bnb. It made me feel a bit of pressure to make sure I was on time rather than being relaxed about our arrival. A key pad lock box is often used by other owners and makes things simpler for all I think.
