Gilbert's apartment is a great place for the first time visitor or someone who knows Paris well. First, it's in an amazing location in the 6th arrondissement (neighborhood).
The train from the airport is a 2 minute walk from the apartment, so we saved 50 euros by taking the train instead of a cab. There are also several other metro and bus lines within a 5 minute walk of the apartment, so we were able to get to all parts of the city pretty easily.
The apartment itself looks directly onto le jardin de luxembourg, the second largest park in Paris. A wonderful place to stroll and picnic and people watch. It's an amazing view. Also several grocery stores and restaurants nearby.
The apartment is large and airy and has a wonderful French feel. The master bedroom is large, but the second bedroom is a very small room that has a loft bed (meaning you climb a ladder to the bed). It's not uncomfortable, just be aware.
Gilbert was very kind and provided contact information if we needed anything. We didn't have any problems, so didn't need to call.
Would definitely stay here again!
