The house is vey clean, spacious and very comfortable, even for four people. The check-in and check-out were very easy. We did not meet Marietta but his son-in-law Juan, who opened the door and gave us lots of instructions about the use of the house. He was also very quick to help when we needed some help.
The area is not very central but well connected with Manhattan through the metro line. You need 20-25 minutes to get to Lower Manhattan by metro (2 blocks from the house). In the evening we did not trust to take the metro and used the taxi to get back home: we paid 20$ from Lower Manhattan. The surroundings have been improuving in the last years but still you should go around carefully overnight.
