This is a terrific building. Apt. 622 would be on the 6th floor. This is a former hotel, and so the numbering would reflect that. This is a fabulous location. We call lower 5th Ave. by Washington Square Parkl the "Gold Coast."
I see that you are asking several questions about different apts. this morning. I would stronly suggest you consider working with a knowledgable agent. We have a very up-to-date and comprehensive database, can help you focus your search and negotiate on your behalf. We take you through each step of the buying process and handle all the little obstacles that inevitably come up along the way. The sellers have agents and so should you to level the playing field. Having been in the two buildings I have answered you on so far (I haven't gotten to your third questionof the morning yet) makes it clear how helpful an experienced guide could be to you.
