Amel's place was very convenient to get to from the airport. The RER train goes all the way down to a stop two stations from Alésia; and from there, it's just a hop on the metro. The flat was very quiet at night so I was able to sleep well. I enjoyed the little balcony too, and it was fun to see the top of the Eiffel Tower lit up every night.
Amel had pretty much everything you might need in the flat (extra plug adapters, blow dryer, kitchen supplies, towels...), but if there was something you needed or if you wanted to buy groceries, a Carrefour (decent supermarket) was a five minute walk.
I also found it quick and easy to jump on the Metro every day and get to where ever I was going in the city. And I never felt hesitant walking around the area alone after dark--the street is well lit.
Also, Amel was very quick to respond to my inquiries and always helpful if there was an issue. For the price, this place was totally worth it! I would definitely stay again.
