We had a great time at Ives' apartment, The location is perfect, close to everything by walk. and 3 minutes away from a Metro station.
The apartment is on the 6th floor (the building has an elevator), it's full of sunlight and an amazing view of the boulevard.
The air condition worked fine, and it was necessary for us in July, the sofa bed is really comfy with white bed linen and towels like in a hotel.
The apartment is a bit small (like all the apartments in Paris) but for a couple, it's more than enough. it was super clean and provide us with everything we needed.
Ives' team were very nice, responded quickly and helped us with every issue or question we had. very recommended.
