I really had a wonderful stay at Csaba's home for the past 3 days when I was in Budapest.
Csaba was a very good host: friendly and accommodating. He provided me with excellent local tips (best tourist attractions, where to buy sim/traveller's card, etc) which made my 3-day stay in Budapest a lot better. He also has good english communication skills so we were able to talk a bit about what we do for work, etc.
The room is very nice, and is perfect for a single or two occupants. There's heater when it is cold and refrigerator where you can store your perishable goods.
The location is easy to find. It is very quiet as well as accessible to: (1) bus/trams going to the city center (about 20 minutes); (2) local grocery store (about 3 minutes); and (3) medicine store (about 5 minutes).
Overall, Csaba's home offers a great value for money and if you are looking for something nice and quiet. I highly recommend this place if you are travelling in Budapest soon!!
