Absolutely outstanding flat! My fiance and I stayed here for our honeymoon and after literally months of trying to find the perfect flat we stumbled upon Lina's and never looked back.
The location is PERFECT! Safe, just out of the tourist bustle but still in a fun and hip area. Couldn't recommend it more! Went running along the river in the mornings (a 3-5 min walk from the flat), close to both the Bastille and the Breguet Sabin metros (Lina recommended we take the Breguet stop to avoid the crowds which was great) and close to amazing bakeries, restaurants, and shops. Le Chat Noir is a great local natural wine bar, 10 belles is awesome for lunch and breakfast and Café Méricourt, along with its grocery, are all amazing. Monsieur Poirot is also super casual and comfy with great food. I would suggest skipping Carrefour City for any items. We bought wine, produce and even bandaids here, all of which were not high quality. The Bastille market on Thursday is definitely worth checking out to pick up all sorts of fun produce and cheeses.
Lina was very responsive, replying at least within the hour for any issues we had. Explained how to use the stove and heater for us very easily and even left us flowers and a welcome note! Her flat is gorgeous and even better than we could have imagined. Many Paris flats seemed to have small bathrooms without a tub but Lina's was beautiful and tastefully renovated. The toilet is separate from the bathroom sink but we didn't mind this at all. Her kitchen was stocked adequately and her silverware is beautiful!
During our trip there was construction going on above the flat but Lina mentioned it before our stay and it wasn't really an issue as we were out most of the days exploring gay Pari!
Truly could keep raving about the flat but you'll just have to experience it for yourself. Would definitely stay here again and tell everyone I know to stay here as well!
