First - the host. Monica is a wonderful host. Communication was impeccable and quick. She gave us step by step instructions on how to get from our train (we traveled from Munich) to the Metro to the Flat and then how to get into the flat. We asked for restaurant recommendations for our last night in Paris. Again she went above and beyond. She gave us location, price, atmosphere, etc. She even offered to call for reservations. Lastly she arranged a taxi for us to get from the flat to the airport. All of this while her Aunt passed away and she was actually in Milan.
Second- the flat. Clean, bright, open. It's small but perfect for a couple or even a small family (maybe 1-2 young children). It was a very nice place. She even gave us a bottle of champagne (it was good bottle too). It had a nice kitchen, sitting area. The bed is elevated, so if you have trouble with "climbing", there was a daybed in the main living area.
Third - the experience. You are in Paris!! There is a bakery on the first floor. It was delicious. My husband and I like to walk, so we got see a lot of things. However if you prefer not to walk long distances, you are not very far from the metro. Monica even made recommendations on what type of tickets to buy to use the Metro.
We are already planning our next trip here. If this space is available, one should grab it. You won't be disappointed.
