Since the OP is apparently going to a location with many hotel choices, location is obviously a big consideration, not only proximity to the business location but also neighborhood amenities and attractiveness.

Something that might be a plus for a few properties that one wouldn't otherwise think of is whether the hotel shares a location with another hotel so that the amenities of the full service or more expensive property transfer to the extended stay or cheaper place. For example, in Minneapolis that's a Residence Inn that's co-located with a Renaissance Hotel (at the Depot). This means that the RI has room service from the Renaissance restaurant, an attached bar, a better business center, a sundries store, valet parking, etc. through the attached hotel. Sometimes the other hotel is across the parking lot, but it mostly matters when the buildings are attached and there's an indoor public walkway between the lobbies.
