Questions regarding address from 1922 Passport

Greetings,

I have located my great grandfather’s emergency passport application from March 1922. The passport application states that he was born in Pennsylvania in 1903 and then went to “Hungary, now Czechoslovakia” in 1905. He applied at the American Consulate in Prague, Czechoslovakia and provided the following address:

Maly Gesti 28 Posta Abraham Bratislavska zupa, Czechoslovakia

I have tried searching “Bratislavska zupa” and this appears to relate to the present day Bratislava portion of Slovakia, but I am not sure that even this information is correct.

Can anyone tell me more about what this address means and the name of the area that it would correlate to now?

Thank you
