Well done you for keeping up your native language, that certainly makes things simpler.
Living in Boston and doing remote sessions in Bulgaria would be an unusual approach to remote working as we usually prefer to live in the cheap place and have rich clients overseas. :-) But I'd guess it was possible, if that's what you wanted.
I popped over for a few days in Plovdiv merely to meet my immigration attorney and get an EU residence permit before Brexit slammed the European door in my face. But I enjoyed my few days so much that I left my job and flew back a few weeks later, and stayed. I'm a former ski bum, and now just a lazy old bum... and I'm too poor to live in Marin County or Tahoe, so I've found Bulgaria rather suits me.
Here we have a very nice city apartment in downtown Plovdiv, just minutes walk from three large parks (Youth Hill, Alyosha Hill, and the Regatta/Maritsa River). As a former European Capital of Culture, Plovdiv has become a delightful small city and a great place to live. Obviously, I can't say it's better than Boston, Chicago or San Francisco... but I'd have to spend nearly 10X more to get an equivalent apartment there. We also have a holiday studio in Bansko, which has turned into a very charming town next to the spectacular Pirin National Park. I used to ski in the White Mountains and Tahoe, and a vacation place there would be similarly prohibitive. In terms of bang-for-my-buck Bulgaria has been an absolute revelation.
I come from a country with a socialist medical system (like Bulgaria) so the USA seems like a medical anomaly. The astronomical costs of its healthcare are a real concern as you get older. In Bulgaria, I pay $20 a month to be fully covered in the public system and get free or nearly free treatment. Plus, private hospitals are affiliated with this system, so I enjoy VIP private care for a minimal surcharge.
Plus... good weather, nice people, wide open spaces, beautiful scenery and National Parks, high-speed internet, fresh, wholesome food, low crime, EU membership and easy access to Europe on low-cost flights by WIzzair and Ryanair. What's not to like, eh?
