Our stay in the Lower East Side was the perfect way to get to know New York. Charlotte's apartment is very comfortable, the bed is especially comfy and the couch good for reading. Charlotte was a great hostess and we took up her suggestions for a number of things and were not disappointed. The best thing for us was the cluster of small theatres around the area - in 4th St and Ave C and other places. The performances were all excellent, not expensive and easy to get in. Our favourite eating places were Lucien, Ed's Lobster Bar on Lafayette and Cornerstone around the corner. If you need a facial I can thoroughly recommend Tamago skincare on East 13th street.
One thing to consider is the two flights of stairs could be a problem for older people.
