We received the keys from the agreed location without a problem and were able to drop off our bags. The apartment is in a fantastic location, very close to The Louvre, Pont Neuf and about 20 minute walk to Place du Concorde and the Champs Elysees. For this it is perfect and initially the host's family were very friendly and welcoming.
However, the apartment is situated directly above a mexican restaurant and kitchen which were open on the night we stayed. The noise from both was excessive - not just the usual noise you'd expect from a restaurant (people, music etc) but also the metal doors of the kitchen and store rooms being slammed, kitchen staff shouting at each other, pans clattering etc etc - this went on until the early morning and myself and my 2 young children barely managed more than 3 hours sleep the whole night. It ruined the following day for us because the children were so tired.
When I raised this issue with the host upon my return he was very unsympathetic, rude and accusatory. Air BNB had to get involved and have since resolved the issue.

I had a very poor experience here and would recommend anyone thinking of staying here to find out if the restaurant downstairs will be open during your stay. If it's closed then I would recommend it for the location and in theory, as it is up a quiet one way street, it should not be too noisy. However, if it's open then I would suggest you book elsewhere if you want to sleep.
