I had a lovely stay at Elio's place.
I booked this room because of its good connections to Roland Garros and flexible cancellation policy. When my friend decided last minute to join me, Elio was so easy to contact and he allowed this with just very little extra cost. As my friend needed to stay a day longer than what I originally had booked for, and the same room was no longer available, Elio even offered another room in his apartment. In the end though, we had to turn down this nice offer, and had to cancel the last day of my stay at Elio's instead (I stayed for only 2 nights instead of 3), and Elio so generously gave me a refund for that last night. I really appreciated it.
I had also informed Elio early on that I would not make it to the usual check-in time, but he said it was fine and he waited for me patiently on that day. He also gave me all the necessary instructions on how to get to his place the day before. When I arrived, he made me feel at home, and also took the time to practice using the keys in the building with me. The day after, he so kindly brought me to the bus stop, so he could be sure that I would not miss the bus to Roland Garros.
Overall, it was a very pleasant stay, and I would not hesitate to recommend Elio's place.
