I enjoyed a good stay at Imane's St Germain apartment whilst in Paris for work. As others have mentioned the location is great, easy walking distance to key parts of the neighbourhood (Le Bon Marche, Cafe de Flore etc.) as well as a small corner grocery store and bank/ATM.
The apartment is very clean and nicely appointed with new fixtures and fittings, and touches like bathrobes and a cleaner make for a comfortable stay, not unlike a hotel. Imane and her daughter were welcoming and easy to communicate with throughout booking and my trip. For me, I prefer an apartment with a view and more natural light, (which with the apartment on the ground floor receives little to none) but that would be the only thing that would make me hesitate to stay here again. A perfect place for a short stay in Paris!
