We went on Berlin for a business trip with my co-workers ; Nino asked a lot of personal information such as our adresses and date of birth - something that no-one as ever requested. There was also a lot of instructions that the team needed to fill-in before arriving as well as a lot of instructions within the flat that were stressful. I wasn't able to attend the trip and my corworkers complained about the Nino's communication and were upset about this. They told me that aside this difficult communication the flat is perfect - clean and they spent a very nice moment there. Everything is as in the pictures.
I would recommend Nino's flat for sure if you don't mind a lot of bureaucracy and personal requests ; or if Nino decide to chill a little :)
