We loved staying in Lisa's flat! We were so surprised to find the room to be nice and big and loved being very centrally located. Lisa was an amazing host- so accommodating to us and even filled up our water each day, took our trash, etc. The apartment is shared with Lisa and one other tenant, but this did not serve as a problem whatsoever. The only issue we had was that it did get quite hot at night on the nights it was exceptionally hot in Paris. There was a fan in the room which helped a bit, and Lisa even offered to buy us another fan which was so kind. Being from the states I think we just weren't used to the heat without AC. Luckily, Paris cooled down later in the trip and so did we (thanks to the fan and leaving the Windows open). Twin beds were comfy. There is a tiny bit of street noise given the central location but this was not bothersome at all. Again, loved Lisa and her place! Such a great Parisian experience!
