Great location, is very central and is close to the main metro/railway stations. it's possible to leave the baggage in the office before check-in which is also convenient. The apartment was clean, just as displayed in the pictures. Good communication with the office representatives, we had some issues with wifi, but it was fixed very fast. Overall we enjoyed our stay.
Keep in mind that the apartment is located in a very central part of the city, there are a lot of restaurants and bars around so it might be noisy sometimes. The door to the apartment is located just next to the entrance door to the section of the building and it was not fully comfortable to sleep in the leaving room as other guests were slamming the door during the night (and speaking loudly while entering). Also, there is a small kitchen but the basic things such as coffee, tea, salt, oil, etc. were missing, I hope the company will fix it in the future.
