My husband was recently a patient at Johns Hopkins - our experience was wonderful. Every person we met at the hospital was helpful. We are not from the area - the hospital assisted us in making hotel and transportation decisions. When we arrived early for pre-op reviews - they took us early. The nursing and technical staff are very professional and respectful of their patients. The facilities are very well maintained, clean and attractive.
Access to the hospital is easy, there is plenty of parking at a fairly reasonable price. If you intend to park for a number of days, or require a number of visits - you can purchase discount parking stamps for $5 per day no in-out (minimum purchase is 5 stamps) There is a metro stop on-site, taxi stands, and bus service.
Although we have major medical centers nearer to us, I would only use Johns Hopkins for all serious illnesses.
