Jonathan's apartment in Paris exceeded my wife and my expectations in several ways. Location - Between the Gare de L'Est and the Gare du Nord, a five minute walk to either of them, and the Metro stops within them. We arrived by train and departed by train and it could not have been more convenient. That being said, we heard no noise from trains. The apartment, being on the 5th floor with good windows, isolated us from all noise, street and otherwise. We slept with windows cracked and no problem.
Furnishings - we stayed in the apartment 11 days and it served us very well. This is an apartment that Jonathan lives in, not just rents out, and so it had everything we needed to stay for an extended period. The kitchen had everything needed to bring food in and cook, the bed was comfortable, the living room was equipped with a new 1080p video projector with a chrome cast dongle. The wifi was solid and fast. We were able to stream video with no issues. We had a couple of cold and rainy days and it was great to be able to stay in, cook and watch the projector. There is a nice balcony for those sunny days, large enough for two of us to sit out, have a drink and look at the rooftops of Paris!
Our host - Jonathan was out of town for the duration of our stay, but he was in almost immediate touch via Airbnb messaging. We had to re-arrange our arrival literally hours before our plan and he worked back and forth with us to have someone at the door when we finally arrived 24 hrs late (a delayed German train - unbelievable). When we return to Paris we will be checking with Jonathan to see if his apartment is available.
