We stayed at Bernhard and Frederique’s place with 6 adults, one kid, and two toddlers, and it was wonderful. The place was super clean, was well laid out for large groups, had a bunch of necessities like shampoo, hair dryers, salt and pepper, Kleenex, paper towels, etc., had tons of dishes and cooking tools, was super stylish, and was in a great location on a trendy street with a metro station nearby. The apartment had a pack and play for out toddler to sleep in (and Bernhard and Frederique actually even provided us with a second one that wasn’t being used in one of their other spaces for our other toddler), and had a booster seat as well as some kids toys. Check in was easy and Bernhard and Frederique were always available immediately if we had any concerns or questions. We would definitely stay here again and recommend to others.
One note on accessibility, this second floor apartment is only accessible via a set of outdoor stairs, so make sure that works for you. We travelled with strollers and needed to carry them up the stairs, which was okay for us, but may be hard for others. Also, note that the metro station near the apartment does not have an elevator (at least not that we could find), and stairs or escalators must be used to get to it.
