I stayed one week at MaryEllen's home. She and her husband were really flexible of checking in and out. During my stay I could come and go like I want because of my own key. As I was on the way all the time, we didn't see us so often, but nevertheless we had some nice talks. Otherwise the family accepts my private sphere, so I felt really well at their home. Also the family-dog Freddy is so lovely and good-natured.
Coffee, tee, granola and fruits were available all the time. MaryEllen also made towels and a hairdryer available for me.
Their nice, big flat is well-located at a subway-station and you can reach Times Square in about 20 min. The Central park is in walking distance. I felt safe at their home and in the surrounding area all time. So I can really recommend MaryEllen's home specially for single travellers, because I think you could rely on their help in case of need.
