The location is AMAZING! Not just within the city (which it is) but the building itself is very cute and unique and on a safe and secure street. The apartment was very comfortable and homey. Nice neighbors but feel like the flat is your own. There was a quietness about it even being close to a lot of the action in Paris.
I will note that the water pressure in the shower is poor when warm or hot and we did struggle with the lack of a few supplies. The toilet paper, paper towels, and tissues was mostly gone when we got there. It only lasted us 1/2 a day before we had to buy our own as they did not resupply. It is up 4 flights of stairs. It is a steep spiral staircase which made caring baggage up and down a bit harder.
I really enjoyed staying here and have no regrets. My friends staying at a different location were very jealous and we spent most of our time here when not out exploring. However would not stay here aging if I went back as other locations I stayed in were just as nice or nicer for a lower cost.
