We spent a month at Letensky Montmartre 5 and thoroughly enjoyed our stay. We didn't meet Katerina at check in, but she arranged for our arrival perfectly and even let us check in early (a huge plus after a very long day of travel)! She did stop by later and brought us information about the Museum Night, and was always easy to contact - a perfect and welcoming host. The apartment is quiet and in a great neighborhood with groceries, shops, and restaurants within just a few minutes, and the beautiful Letna Park just a block away. Best of all, we were close enough to walk to the Old Town and Castle, but away from the touristy crowds of either. There was a surprising amount of closet space in the apartment, and the back ivy-covered window made the apartment feel even more like an escape. We can't recommend this place highly enough and would happily stay again.
