Would definitely stay again! Beatrice was waiting for us when we arrived for an early check-in, and the location is absolutely fantastic: within 2 minutes you are at Place Dauphine and within 10 minutes you're at Notre Dame. The streets surrounding the apartment are full of cafe's, bistros, bakeries... lots to explore. Saint-Michel, Saint-Germain-des-Prés and Châtelet metros were all within walking distance. Everything in the apartment was clean and comfortable. We were there in December and the apartment was toasty. Plenty of hot water and clean towels, the beds were comfortable. We considered it our exercise having to carry our suitcases up 4 flights of stairs, but you only have to do it once and then you're done. Massage at Ban Thaï Spa, literally next door, was great.
