The location of this apartment is its best attribute. It is located near Opera station and offers easy access to most tourist attractions in Paris. The suite itself is located on the fourth floor attic and there is no elevator so beware if you have heavy luggage.
The host used to live in the suite and a lot of his personal belongings are still in the suite which gives it a lived-in artistic studio feel. The suite has two levels, first level contains the kitchen, bathroom and living room and second level has a double mattress on the floor for sleeping and is accessible via a steep ladder. The second floor and the living room area have low ceilings. I'm 6'1 or 185cm and I couldn't stand up straight on the second floor and my head was a few inches from the ceiling in the living room. Not a big deal for our short stay but it could be a problem for taller travelers.
The bathroom was nice and clean and well stocked. Towels, shampoo and hair dryer were available. There is also a large washing machine and laundry detergent.
The kitchen was well stocked as well but was lacking in cleanliness. The fridge contained old and expired food and mouldy stains when we arrived. One of the kitchen drawers hasn't been cleaned in a while and small bugs crawled around the bottom of the drawer.
Other area of the suite were a little dusty and there were a few moths flying around when we arrived. I killed a handful of them the first night and that alleviated the problem.
The host was responsive and helped troubleshot the TV and reset circuit breakers in a timely manner. He also accommodated our late checkout request.
Overall, this apartment is a good option for budget conscious travelers looking for a central location to crash after exploring Paris.
