You can't go wrong staying with Yves. No surprises, great communication, appropriately flexible to manage arrival and departure times. The apartment will likely be exactly as you expect or slightly better. Décor is clean and pragmatic and amenities for kitchen etc. just right. Really like that the place has a washer and dryer as this can allow you to travel lighter and wash after a few days and not have clothes cluttering the place while drying. Marais as a destination to stay in Paris is great and the apartments location is fantastic within Marais. Recommend bringing a pair of trainers to head around the corner to Place des Vosges for a morning workout!
