Unfortunately we never got to meet Sonia, but she left amazing instructions on how to access the flat and was a wonderful host throughout the trip with prompt communication. The flat is just lovely and very spacious with a perfect view of the Eiffel tower. We spent several nights sitting on the sofa watching the tower lights twinkle. The flat was very clean, has wonderful light throughout, and everything you could possibly need is there. I would highly recommend staying at Sonia's and I'm sure we will be back again.
