It was nice flat for my family (3 people). It's near Effel Tower and metro is located in walking distance.
Room is cozy and compact (i think it's better for 2 people). Tableware are for the same number of people and utensile is (pot, plates, cookers and so on), plus refrigerator.
Shower works well and power of shower ing water is good as well.
There are big windows and it has no problem on ventilation after shower and cooking (actually i didn't cook during my stay).
