The Pros - This place was in a great location and the host's were very personable. I truly enjoyed the space and the apartments closeness to everything we cared to see. I thought it was extra nice that the owner reached out several times prior to our trip to give us tips about places to go and see in Paris. Those little things made this owner standout.
The Cons - The bed wasn't the comfiest as you could feel the springs and it felt as if there was a bit of a hole in the center of the mattress and the shower is rather small. I am 6'1 215 and that's about the maximum size that shower can hold. Anyone with a larger frame will have a tough time cleaning themselves properly. The only other aspect to be aware of is the apartment is up 4 flights of narrow stairs. We didn't find this to be an issue although those that travel with large pieces of luggage could see this as a challenge.
Knowing everything I now know about this apartment I would absolutely choose to stay at this location again should I find myself in Paris.
