Hi,
In terms of picking up work, yes it is very easy at this time of year, especially in the leisure, dining and nightlife sectors. If you check through the forums on here, there are threads by local recruitment agencies such as Wemploy.com listing jobs available.
Accomodation is also a lot easier than you think. YourMarbella members Evie and SarahJL found eachother looking for flatmates on YourMarbella as have many others in the past. If you are not looking to share then check our real estate sub category in our business directory and you will find a host of agencies listing rental properties available in the area.
Good Luck!
Christian
