E's place is wonderful. It's located on a side street that is private and quiet yet also central to everything. It's very close to the Marchais des Enfants Rouges which is very cool. I think many people would be jealous to live that close to the market. Everything you need is nearby: pharmacies, post office, cash machines, bistros, coffee shops, grocery stores, parks, and metro stops.
Besides the location being amazing, the apartment itself is awesome. It's in a very friendly and safe building. It's on a high floor with a reliable elevator. The apartment has an authentic French style with beautiful windows that open up where you can see the amazing sky and clouds. The kitchen, bathroom, and WC are all stocked with exactly what you'll need. There is no clutter. The water pressure and hot water were never a problem for the shower/bath. The place is beautifully decorated.
As a host, E. is extremely responsive and provides multiple ways to communicate with him and others that can provide assistance if needed. E. provided helpful recommendations. For example, I wanted to go hiking and he suggested Fontainebleau. A map of the forest was even available for me to use. E. provides detailed written instructions too that I printed out and referred to as needed.
If given the opportunity, I would definitely stay at this lovely apartment again. I recommend it highly to everyone. Stay here, you won't regret it!
