We had a lovely stay in Malaga with the family: 2 adults, 1 baby (11 months) and our daughter of 3 years old. The apartment was really big, with rooms for each of us and the location was nice, right in the center with plaza de merced around the corner. I would recommend it for holidays with older children though (or with a group of friends). In our case, with small children, I felt the apartment was lacking some things (a good table to eat at; proper chairs to sit on; there was no baby chair). The baby bed was not there when we arrived but Patricia helped out really quickly and was really communicative, which I really appreciated.
Cheers!
