For long term stays consider corporate housing that offers additional amenities such as spas, hot tubs, on site pools, exercise rooms or even golf courses or other recreational attractions close by. Remember that weekends and holidays are times when visitors like to get out and tour and sightsee, so making this convenient is essential.
Check to make sure that the corporate housing facility that you are using is staffed at all times. This provides security for guests plus it makes sure that any needs or concerns will be dealt with immediately and effectively, rather than having to wait for staff to arrive in the mornings or calling an off-site number.
