Staying at Ling Yi's apartment in Cambridge was a great experience all around. His service is outstanding - he supplied the frig with food for my breakfast, he offered help with anything I needed, and he was really friendly in corresponding via text and email. The apartment is spacious and clean, plenty of room for a 2-bedroom apartment, with a great TV and clean kitchen/bathroom. An finally, the location for me is perfect, near MIT, near Central square, easy access to the T and walking distance from Harvard Square (even in cold snowy conditions).
I'll be staying here again the next time I'm in Cambridge for sure.
