Great location in Sofia Center near historic sites. Short walk to major sightseeing spots and restaurants. Good service by the staff. The issues we had was, the back side of the hotel was blocked by buildings. No view at all and we had to keep curtains closed at all times. The electric plug at coffee/tea station was broken, the QR code on TV screen for room service did not work, and when I ordered with menu from their website it turned out the menu was outdated. Small stuff like that. Otherwise it is a great place to stay in the hotel.
