We have a washing machine and tumble dryer so you can pack light. In the spring a hoody or cardigan is always a bonus. Throughout the year I would suggest packing mosquito spray. Some members of my family seem to attract them all year around. The spray helps!
The apartment will be ready for you with beds made and towels provided for the bathroom. We do not, fodd bynnag, provide beach towels so I would recommend packing a few.
We have a Dolce Gusto coffee machine which works a treat. You can buy the pods locally or i do suggest bring a packet with you. They can be bought in any major supermarket and it means as soon as you arrive you can have a nice hot drink!
