This is my second time staying at B1, but this time I stayed longer and worked during my stay. I've had several hotel experiences in Sofia with bad Internet but this wasn't the case here, which I was happy about. I was able to work and have Zoom meetings with no issue. My room was on the 6th floor and I liked the view as well as the quiet. The hotel is new and looks it. The room is minimalist, which worked for me. The only minor thing I'd recommend they do differently is that there's no need for that many snacks, both in the mini fridge and on the counter. Because there's limited space to store my clothes, I'd rather have the space on the counter for that. Not a big issue, though, and I was thrilled with my stay. Will come back for sure!
