Late May to early June...
Sofia felt like a normal day in a European city.
I easily had a front row place to watch their (admittedly smaller, but still impressive) Changing of the Guard.
I walked right in to every museum. No reservation required. I had entire museum rooms to myself during my visits.
Popular restaurants did require a reservation, for dinner (not lunch) though I only heard Bulgarian. After repeat visits, I got to know the welcoming staff who smiled and remembered my preferences from a prior visit.
Plovdiv seemed like any normal day. I was annoyed when the one other visitor to the Hindlayan House was in the same room that I was 🤣
For dinner in Varna, we had our pick of outdoor tables at the beachfront restaurant on the Black Sea.
Veliko Tarnovo's craft market street felt empty.
Skopje on my single day, mid week visit was alive but nothing approaching crowded.
