I can warmly recommend Lines appartement. It‘s a nice and cosy place, mostly quiet (sometimes we could heard the neighbours upstairs walking and talking). For my wife, me and our teenager daughter (she was happy to have her own bedroom) it was perfect. In the evening we loved to sit on the balcony in the quiet backyard listening to the blackbird singing. There are many restaurants and places to go around the corner and with bike, metro or bus you are in a few minutes in the more touristic sites.
