The apartment is incredibily well located, in the heart of Saint-Germain-des-Prés. While the building is beautiful and features two very well kept old elevators, the apartment is not particularly stylish. For example, the lights are very cold and the couch is the standard black synthetic leather one you would find anywhere.
However, the customer service is remarkably efficient - Every time I needed anything, for example an extra blanket or two extra pillows, I was answered very kindly and quickly and provided with what I asked for.
