You would only reserve a room, but the hosts do not live there and the chances you would meet the other guests are very slim, as anybody has different times and people in general do not spend much time indoors, in a place like Malaga. This means you are likely to get the whole house for yourself (including kitchen, lounge and bathroom), for the little time you would want to spend in it. Of course it is also nice to meet the other guest, but it will probably be just saying "hola" when crossing them on the staircase. The location is great, right in the middle of the city centre, with supermarkets next door.
