I stayed for two nights as part of a business trip. Studio is stylish and convenient for a short stay in Berlin. It is clean and has the basic necessities. The most amazing part is that you are actually staying within the premises of the Berlin Wall memorial! So you can already cross out one of the sightseeing places to visit. Few minutes walk to public transport (bus, tram and metro station). Some restaurants close by and a souvenir shop. Finding the appartment is a bit tricky as it is not on the main road. However not impossible ;) took me few extra minutes. Hosts are friendly and available for information. Very good wifi connection. I recommend.
