We stayed at this apartment as two adults and a toddler. The provided crib and high chair were great, as well as the sheer amount of space. Our son loved the outdoor patio. Location was excellent for exploring and a short walk from the metro.
Our biggest concern was that some necessities were in short supply. There were no dish towels in the kitchen, no linens on the second bed, and we ran out of garbage bags after 2 days. We would up removing the sheets covering the couches to use in our toddlers crib after he was sick. In addition, the elevator was too narrow for our stroller to use, so we had to remove a wheel or drag it up the stairs.
Noise level is a little high for those with young children. Despite using a white noise machine, the sounds of the neighbors were very easy to hear at all hours.
