We had a lovely stay at Celia's place. Communincation prior to arrival and then during our stay was excellent. The photo's show the apartment accurately and it is a clean and well presented apartment.
The access with the elevator was great with lugguage up to 4th floor.
The Metro directly outside the front entrance was very convenient, and it was our main mode of transport in Paris.
The wifi was weak in the bedroom from our experience, and just something to be aware of, although in the living area it was okay. This is not something that would stop me staying here but to be aware of.
We would happily recommend staying here!
