To make an appointment at the at The Spa at Four Seasons Hotel Baltimore, call Four Seasons Hotel Baltimore at 410-576-5800. The reception staff is well versed in each of the treatments and is eager to guide you in securing the remedy for your needs. It is best to reserve an appointment as far in advance as possible, especially if you want a spot during the weekend or holiday periods. When booking, you will be advised to arrive at least 30 minutes prior to your treatment to complete a questionnaire about your skin and general health. The great thing about being a guest at the Baltimore spa is that you essentially have a free day pass to the entire facility — including the hot tubs, sauna, steam room and the outrageously decadent heated loungers. And speaking of free, spa guests also receive complimentary valet parking.
