Espresso Embassy has great vibes with perfect espresso. You get fast Wi-Fi signals and power outlets all over the place.
Cirkusz is one of the best place to work from with super fast internet up to 105mbps. It cost around 6$ a day.
Telenor- offers very good service with nice plans. The staff is great too.
They have daily passes at 10 euros, also with 5/10 day options. They have meeting rooms and lots of community events that makes this place my favorite. Kaptar is another nice coworking space to check out.
My favorite cafe to work out of Budapest. They have fast WiFi, plenty of power outlets and a really nice coffee tho it is slightly pricey. Many students work out of here. They have two outlets in Budapest.
Best tip about Budapest: Digital Wombats. It is a group for Nomads. We meet, share experiences, learn and enjoy.
Impact Hub Budapest - One of the best coworking space in Budapest! Very spacious with natural light, awesome community, great events, central location.
