We loved our stay in the South End. The space was clean, quiet (at least as quiet as can be expected for a front street location) and attractive. The location was great - steps to groceries, restaurants and a few blocks to a Bluebike kiosk. The four floor walk up with suitcases made for a bit of a tough arrival with suitcases. If your knees are bad or your suitcase heavy, you might want to look at a lower floor unit.
