A few blocks from Puerto Madero and the shopping on Calle Florida, this business-friendly central hotel feels new even if it's now nearly 10 years old. The Regal's expansive rooms have enough space for even short-term travelers to spread out and relax. There's a small but tranquil courtyard with a pool and a standard restaurant that can't live up the standards of nearby Puerto Madero but will do for a business lunch.
