We had a wonderful stay at aeki City gallery. The hosts were very accommodating and professional. Communication was smooth. It was extremely convenient that we could leave our luggage before checking in and after vacating. The apartment is enormous. Very spacious rooms. Excellent central location close to almost anything (given that it is also right next to an Ubahn station). There are the typical city street sounds at night but that was to be expected at such a central location and it didn't bother us. It was convenient that there was a large cafe on the ground floor of the building (we had breakfast there once and dinner once). I was on a weekend away with 6 friends and everything was perfect for us.
