This flat is located in a quiet side street of the Marais, but it is a great neighborhood and near subway and bus lines to get you around the city easily. There are a number of excellent restaurants, shops (including food markets) and patisseries within walking distance. It's an area worth exploring. The wonderful Marche des Enfant Rouges is only a block away.
The pictures of the flat are accurate. The bedrooms are on the second floor, which has a low ceiling and exposed beams. It is a basic and comfortable flat. It was generally quiet.
The host is quick to respond to inquiries and the check-in/check-out process, through a company, was accommodating and responsive.
