We recently stayed at Chiado Mery - Lisbon Best Apartments as a family, and couldn't have been more impressed. The apartment was clean, nicely appointed, and our special requests (crib & highchair) were there without issue (which as other parent travellers know, can't always be counted on!) They even went so far, as to leave a little gift teddy, for our young son, which he loved and was a special touch. Excellent area, lovely apartment, would love to stay here again.
