The apartment is very much exactly what it appears to be online. It is clean and comfortable. The flights up the stairs were steep as described...the U.S. typically considers the ground floor to be floor 1, but evidently in France it is Floor 0, so when they say 4 flights up, it is in fact 80 steep steps. Every device was in fine working order. The washer/dryer is one machine, which does both....pretty cool. The only challenge is that the wash cycle took nearly 2 hours and the dry cycle over 3 hours.
The location is right in the heart of the Latin Quarter, which is very exciting. Everything is accessible with great ease...the Metro, the Seine, restaurants, shops, etc. Just note that the apartment got warm, and the temperature was in the low 70's. We needed to open the windows.....the first issue is that the Latin Quarter has a very loud party atmosphere that goes until around 2am every single day, so that can be disruptive for sleeping purposes, unless you are out enjoying the nightlife. The second issue, is that the smell of cigarette smoke was constantly coming in through the windows, which we didn't enjoy. We were never sure if this was from the street level, or smokers on lower floors. That certainly is not the fault of the owners...just a caution to potential visitors, if the weather is warm, and open windows are needed.
