I had a fantastic stay in Paris at Sandra's home. It is in a perfect location. It is a few steps from all the action, but set off just enough to be quiet. The bedrooms in particular are angled off from the street so a quiet night's sleep is assured. Upon check-in, I had a problem with the internet due to some nearby construction, but Philippe immediately provided me with a backup router which worked perfectly. The metro does run under the building, but literally, it is no distraction at all. It doesn't run late at night and during the day felt as nothing more than part of the normal rhythm of Paris. I hope to be back very soon.
