Dear Romain, we are very, very sorry we didn´t manage to get an electrician during your 3 day stay. Most people like the direct and keyless entrance to the apartment, so we are sorry this was not the case for you. We put a lot of work and thoughts into establishing the apartment, which yes, was a former shop originally - but you may admit this is not noticeable any more except for the old entrance door. We will take care of your criticism points concerning heat in the apartment - it is an extraordinarily hot summer in Berlin with hardly any rain and temperatures up to 37°C - this is not normal for our city. Another point that you mention: the neighbourhood in the house had to experience partying guests in our apartment right in the beginning (which is strictly forbidden in our apartments) and therefore asked us to take steps that would prevent any further disturbance of the community. There is nothing wrong with that to my opinion. Again, we are very sorry we seemingly did not meet your expectations, we never got a review like yours for this apartment, so we are pretty sad...still, we wish you all the best!
