There are plenty of washing machines and lots of folding space in this bustling laundromat on the Park Avenue end of Phoenix Avenue. There is no air conditioning, but a number of large overhead fans keep the air moving on hot summer days. Both 25- and 40-pound machines are available for cleaning comforters and featherbeds, and laundry can be dropped off at this site if you don't have time to do it yourself. Mr. Clean offers a special car- and boat-cover cleaning services and will also tackle horse blankets and other heavy-duty jobs.
