I really enjoyed my stay at Daniel´s apartment for one month. The communication was well so that I directly got an answer when I had a question or a problem. For one person the flat is absolutely sufficient in my eyes and you find everything you need. The room was very comfortable and welcoming so that I felt at home immediately. In particular I was positively surprised by the comfortable bed combined with a coach and the clean and modern bathroom. The only point to consider might be that the kitchen is not that big with two cooking hobs as you can see on the photos so cooking sophisticated meals might become a bit difficult during a long-term stay.
Nevertheless most important and positive to mention about this apartment is its location right in the center of Paris. You have everything you need around you, many of the most famous sights within some minutes by foot and for all longer distances there is the huge metro station "Les Halles" connecting several metro lines in every direction just around the corner.
So all in all I can warmly recommend Daniel´s apartment especially for short-stay trips, but for me the apartment also fitted all my needs for a longer stay :)
