Martin & Co are by far the most professional and responsive letting agent in Cambridge. Having just moved within town, and having had almost no expectations of letting agents after disastrous dealings with other local letting agencies, I was pleasantly surprised by the speed, efficiency, and courtesy of the service. I would highly recommend you use them over any other letting agencies in town, who appear to think of their customers not as clients but as money machines. Martin & Co show it's really not that difficult to have happy customers in the lettings business - reply quickly, behave professionally, and treat your customers like like real people rather than a source of revenue.
