Here's a quick Budapest apartment tour of the AirBnb that I stayed in during my 3 months in Budapest.
Including all of the service fees the apartment came to around $500 Canadian per month. This includes internet and all utilities with the apartments coming furnished and lightly stocked.
This Budapest apartment featured a loft with a large living space and a separate kitchen/bathroom area. There was a courtyard view although the apartment didn't get much natural light throughout the day.
The kitchen came equipped with an electric stovetop, dishwasher, lots of counter space, and it was stocked with some supplies and necessary cooking utensils.
The bathroom was small and came with the tub/shower and washing machine. The window in the bathroom let in some natural light and made it easy to air it out if it got too humid.
For the price I'm not sure you can find similarly priced apartments anymore. I rented this AirBnb apartment in Budapest back in October of 2015 and after checking in December of 2017 I couldn't find anything similar in price.
