Francesco is perfect host and apartment is great. There were not any problems during our stay. Francesco provided very helpful instructions about arriving and living - so we had all information in advance. Communication was also great - Francesco was available by emails, phone and WhatsApp and responded immediately.
Apartment is not huge, but has everything you may need - well organised kitchen, fast WiFi, TV, separate bedroom, A/C (quite loud, but efficient). Bathroom is quite big with roof window (apartment is on top floor). Also it was very easy to ride to any place in NY as 6 line is in 1 minute walk and 3 line in 10 minutes. Access to many buses was quite easy too. Despite East Harlem is not quiet, I can't say there were any problems with noise from the street.
So I definitely recommend Francesco as a host and his apartment is a perfect place to stay in NY. Thank you!
