I stayed at Hervé's apartment with a colleague for a couple of nights and we loved out stay. Hervé was really nice and helpful from the start. He always replied promptly to my queries and tried to help as much as he could, even letting my colleague check in slightly earlier than usual to help us out. He even prepared a nice folder containing instructions on how to check in and out, and local tips, including areas to visit, restaurants, etc.
The apartment is very nice and stylish, with wooden panels and furniture all around. Almost like a mountain cottage/chalet, you could argue. The rooms are very big and we had plenty of space even if there were two of us. The location is perfect if you want to be in the city centre (the place is round the corner from the Gambetta metro station) and still be away from the hustle and bustle of the main roads. Good assortments of shops not too far and the metro is just a 5-minute walk away. Would definitely recommend!
