I can’t recommend this place unfortunatelly . First, it is certainly not suitable for 4 guests - the sofa bed, when opened, has no support on one side, so it falls over even if one person is sleeping on it. It is dangerous for health.
Second, this is not AirBnb, but a company with many flats. It has consequences. For example, when we arrived (at 15:30), the place was unprepared. It took a long time to understand when and if the cleaning stuff is comming and made a “nice” phone bill with Switzerland to me calling 8 times or so. After cleaning, there were still some sheets missing for 3 people…had to call again.
Third, no word of appologie for this.
Forth, the blankets were huge and much too warm for +25 or more degrees. No extra blankets, no extra sheets. Since it was not possible to get any infant equipment (bed/chair) from the stuff, one huge blanket made life more difficult. Etc.
Otherwise the flat is ok, if you really do not need any help from the stuff and the aparment happens to be prepared.
