Great for single travellers! I have stayed here before, alone, and loved it. Close to everything in the city and easy to park.
With a family, thoughy, the room was way too small. We were four people and could not open a single suitcase without putting it on the bed.
Also, the bathroom door does not lock, or even close. Everyone hears everything. After a while you prefer a public restroom to the one in your hotel room.
I would not recommend the Sofia Hotel for families or groups larger than 1 person.
We should have received some VIP Access benefit, which was part of why I chose this hotel, but the staff had never heard of it. There were zero benefits to be had as a Silver member.
