Maria's place is at a great location- just few steps away from the famous Champs Élysées ! The apartment is slightly small- but then you should know how much is 35 m2 as Maria clearly states that. However, if your plan is to roam around in Paris during the day, then the slightly smaller space should not be an issue.
Also, the place gets a little warm during summers (during the day) and there is no air conditioner. However, as we were out by 11 am everyday and were back only by 9-10 pm, it was fine.
All in all, its a good place and value for money given its superior location and ease of communication with Maria!
