Monika and her husband were very friendly and helpful from the first moment, they are very lovely people and were very clear with everything. The aparment could not have been more perfect, it was a very cozy, clean, quiet place, while at the same time being right in the center, Alexanderplatz being 5-7 minutes away by foot. Around the flat there was everything you needed, from restaurants, to bars, to supermarkets. We are very happy with our stay in Monika's place and would definitely go back if we came back to Berlin. I highly recommend it.
