This location was amazing — totally safe, convenient for a handful of metro stations (including RER from CDG airport), steps to lots of great restaurants and the St. Germain food market, and not noisy. We grocery shopped at Monoprix and felt at home.
The five flights of narrow stairs might be a barrier for some but it worked fine for us. The view of St. Suplice was really very nice!
There were a few issues in the kitchen with items not being clean, but they may have been because we requested an early check-in and cleaners may have been rushed. We also did not have toilet paper so we bought some. Those were very minor inconveniences though! Would definitely stay here again!
