Communicating with Mario was very easy. Getting the keys and handing them back too. I never met with Mario in person, but we dealt with everything through whatsapp and it worked very well.
The apartment is located in a very nice and busy neighborhood, with all the students from NYU in the area. There are a lot of bars in the street. It's the right place to come to if you want to be downtown and have fun at night. Of course, with the bars around, there is some noise, but it didn't bother me.
It's very close to a lot of subway lines, and I loved to be so close to Washington Square Park !!!
