Right on Szell Kalman a transportation and shopping hub.
Check out 101 Bistro next door. Great Asian food!
Check out A' Table on Retek a block away. Great place for breakfast.
Farmers market in Mammut 1.
Apartment was right over the bar so noisy revelers to late (3am!) many nights as well as sirens, etc.
A short bus ride up the hill to Budapest Castle.
