Odd that someone would spell his surname (line one) completely in lower case. Also, units are not located "in" a street. They are located "on" a street. However, the custom may differ in the Urkaine and in Nigeria.
There are many rental scams out there - even on Craig's List. I would advise any prospective tenant to transfer funds only after confirming the identity of the building owner. No public agency will provide this information, not even the Rent Control Baoard.
They say that everyone has 4-5 friends and 2-3 relatives in Real Estate. Ask one of them to check an ownership database.
