The studio was just as described, and seen in the picture, favorable FengShui ;) -delightful. Comfortable bed and nice linen!
Ji made me feel very welcome, and made an extra effort to accommodate my early arrival. I appreciated that a lot. When I had a question, she answered her phone promptly.
The studio is located on a quiet side street, walking distance to three Metro stations. Many nice boulangeries and vegetable stands nearby. I found distance from Gare du Nord too long to walk with luggage. Walked to a taxi stand at the station and paid 7euros to the studio. I found Uber enormously expensive!
