I wish I could give the "Dream Tonic" studio seven stars, because it deserves it! It is beautifully clean and extremely well maintained, with everything you need (including items like salt, pepper, oil, tea, and coffee in the kitchen). The location is amazing, easy walking distance to Montmartre and the Champs Elysses, the Opera, and well connected via public transportation (or a slightly longer walk) to the Louvre and Notre Dame.
Nadji is SUCH a great host! He came to meet me at the subway station, gave me tips on where to eat (his favorite neighborhood boulangerie, etc.), provided directions to the airport, and generally made me feel extremely well taken care of and welcomed. It was such a pleasure to stay at "Dream Tonic" studio, and I look forward to my next trip to Paris when I can stay there again!
