Good overall. The staff is excellent. The location is good around 5 min walking to the metro which goes to the center of Sofia for 15 -20 min for about half a euro. Airport can be reached by metro, but you need to change the lines at Serdika station. Taxi to the airport around 8 euro.I wasn't able to adjust the air-conditioning in my room ( facing the street) to a lower temperature and opened the window overnight. It was noisy because of the event downstairs ( I believe the events are mostly on the weekends, but it's worth checking before booking). However, my issue probably could had been resolved, if I called the front desk. I was only for one night to catch an early flight and didn't call.
