It was a pleasure staying at Hong's Studio for a week. I was lost getting from the airport via train/metro and she help me navigate via text each stop to get off on. The location is great, very convenient. On my first day I strolled through Parc Monceau then walk to Ladurée on Champs-Élysées. You are also near Courcelles metro, which was very convenient to transfer metro lines to Jardin des Tuileries and Jardins du Trocadéro metro stops. I am from San Francisco, in comparison of studio size, I would say its average to small which is plenty of space for a single traveler. There are six flights of stairs that were easy to climb up since I only brought a small carry-on suitcase and a backpack.
