A friend and I stayed at Mariko's apartment for a month while working in NYC. Mariko is a lovely host - very welcoming and accommodating and extremely responsive over email/text. Her apartment is clean, comfortable, and well-kept. As noted by others, wifi was sometimes slow (for example, 2 people can't stream video simultaneously) but for most functions was completely fine. Location is excellent: the neighborhood is very pleasant, and the street is quiet enough for sleeping but also close to everything you could need. 5-minute walking distance from both 72nd and 79th St subway stations. We enjoyed a wonderful stay. Thank you!
