It was perfect for us. One-half block from the subway in a real Parisian neighborhood. Great open air market on Tuesday mornings (takes up three long blocks).
My traveling companion is 83. Climbing 50 steps to the apartment was challenging but he did it without stopping (or complaining) each time, including with his luggage when we arrived. I took the loft bed and you need to be agile to climb the block stairs. Yes there is no shower, but the bathtub is large and spotless and there is a hand held shower head. I am 6 feet tall and the bathroom sealing is 5’11” so if you are tall maybe not the best. Furnishings are chic and she has made a very efficient use of space. It was unusually hot in Paris during our stay. I asked about a fan and when we returned from our first exploration of the neighborhood she brought in a nice 3-speed vertical swivel fan. Just what we needed. No problems with the WiFi.
