Residential neighborhoods in Budapest?
 

I will be in Budapest the last week of April. When I visit a city, I like to stroll through residential neighborhoods and look at private homes and flats. Rather than massive apartment blocks, I especially like the big old 3- or 4-storey buildings that were probably once private homes, separated from each other on a leafy block by a bit of space and greenery. Can anyone suggest some neighborhoods in Buda or Pest for my walks?
