I stayed at Sandra's place for about half a month, and was extremely fond of the place, hosts and location! It was my first time in Paris alone, and both Sandra and her mother was very helpful - assisting with any questions or struggles I had, and always available to come and help in any situation!
The space was very spacious, with a very comfortable and large pull-out bed, and a cozy backyard which was also very spacious! The area is great for those exploring Paris the first time, or for long term stays! I was very excited about it being very close to great tourist attractions such as the Sacre Coeur and Moulin Rouge. There are also all stores needed located closely to the studio, with a bunch of cute cafes and restaurants as well. The area felt very safe, and there were always people around, even at night time. The metro station was also only a very short walk away!
Overall I felt very welcomed and at home in Paris in Sandra's studio , so I definitely recommend a stay here!
