Living Hotel Weißensee in Berlin

I spent several days there, but there were problems since the beginning.

To do the check-in, my data was incorrect and the receptionist changed it with typex and a pen, but just on the paper and not in the computer and she didn¡t give a copy or a paper to me. I noticed that when I asked for the invoice, what I did several times and there were always "technical problems".

Moreover, WIFI was opened for everyone and the signal didn't arrive adequately to my apartment. The AC worked, but too noisy (the apartment is from the 60s maybe, it was old).

I didn't receive the welcome bag at the begining and nobody asked for or mentioned it. The receptionist on the first day just mentioned I hadn't booked the breakfast, but not that you can get some things for free at the reception every day in case you need or ask for. She didn't give enough information with the check-in. I had to buy several things and then, they were included.

Another point to mention is that the technical service should come into the apartment and I mentioned what time I would be in the apartment to let him come in and he came in when I wasn't there, what I find lack of communication between reception and this person.
Last but not least, fan extractor in the kitchen didn't work.

However, some staff were nice and the room service too.
Taking into account that it is a four stars hotel, several things should be improved. Other hotels from the same chain are better organised and inform the guests at the beginning.
