Alain's apartment is as presented in the photographs; you really can see the Eiffel Tower directly out the windows (in fact, the view of the sunsets is lovely). It is unusual in my experience to have several separate spaces (living room, bedroom, kitchen, and bath) in a Paris rental, so it made the apartment seem larger and more pleasant. The shower is abnormally large for a Paris apartment, and the hot and cold water were 100% reliable. The elevator worked perfectly the entire time and was large enough for suitcases and groceries (the apartment is on the 4th European floor, 5th floor for Americans), and the new washing machine has a fast enough spinner that clothes are dry within a few hours of hanging them on the rack (in other cases, we've had to dry clothes for a day or two or take them to a laundromat to dry). There is a medium-sized TV but we didn't use it. Wifi was 100% reliable and strong enough to stream video. We've had problems with all of these features in other Paris rentals, so Alain's apartment was easy in comparison and as advertised.
The neighborhood is lively at night. Expect to use earplugs if you want the windows open--you are on a major thoroughfare into and out of the Bastille traffic circle with four late-night cafés within the same block and a restaurant across that street that is used by the "bridge and tunnel" crowd for birthdays and other celebrations, and you are very close to the Bastille monument. But it's a fun and safe part of that neighborhood, and the apartment building is perfectly located for proximity but not living IN the much more crowded or touristy parts of that area. Metro, bus lines, and the Seine are steps away, but you can choose to avoid the fray, too, and wander down to the quieter neighborhoods to the east, or wander the Seine. We have stayed in Paris long-term a couple of times, and while we thought we wouldn't love this neighborhood, we did!
Communication with Alain was always quick and clear, and he reached out to make sure the oscillating fan was working during a major heat wave. We can recommend him as a responsive host.
