Over all our stay was pretty good. However, there were 3 major issues. First of all, the wifi - of which it was said it would be there - was not working. Because of that, many of us ran out of data and had to buy new (expensive) data to make it through the month.
Secondly, there was not enough cutlery in the apartment for 13 people. There were about 3 knives, 7 forks and 7 spoons. This was quite an issue when we wanted to have dinner together. Furthermore, we could not get plastic cutlery from the bar below, as was promised.
Thirdly, the apartment was not equipped with curtains, which meant the sunlight would shine in brightly at 5am already. We ended up creating our own curtains with aluminium foil and fabric.
Lastly, there were some minor things which would have been nice to have: salt, pepper and oil (as was promised in the ad); a brush for the dishes; a dustpan and tin and some extra dishcloths.
Despite these issues, we had a nice stay in Berlin. The appartement had a lot of space and was located in a nice cozy street, with great food. The city centre was also easily accessible!
Kind Regards, Coos and the group
