We had an amazing time staying at Mel's studio in Paris. Mel and her husband were very kind, warm, welcoming and gracious hosts. They were flexible with our schedule and met us at the apartment late at night to give us the keys. They every brought along some snacks in case we could not find a good place to eat given it was Christmas Eve. They were very responsive and gave us great recommendations for the city.
The apartment is located on a well know Paris street with tons of creperies, cafes, restaurants and shops. It's quite touristy - but really in the perfect location if you are visiting: walking distance to Notre Dam, Louvre, Le Marais etc.
Despite being located on a fun and busy street, the noise does not carry into the studio. The studio itself is modern, new and fully stocked. The bathroom shower head is modern, with great water pressure and faucets - which is a real luxury when traveling in Europe. The studio is a little small, with limited personal or common space. If you are 3-4 travelers I would not recommend it for more than 1 night. If you are 2 travelers it is a great size.
Overall we had an amazing time. Mel and her husband did everything they could to make us feel welcome, comfortable and at home. I would absolutely stay there again when I return to Paris!
