Starting with the pros... This apartment is in a great location, near to restaurants and the supermarket. There are steps down to the beach at the bottom of the road too, although we had a buggy so often took the road down to the beach. The gardens and swimming pool are also great and very well maintained.
Unfortunately there were a list of cons that made our stay more stressful than it should have been. The hot water doesn't last long enough for a family of 4 all to have a warm shower (even with everyone rushing in and out) with a 5 year old and a 10 month old this was far from ideal. The electricity cut out every time we tried to use the hob or oven, so cooking for the children was a very stressful experience as the electricity was tripping every 30 seconds. There is no high chair at the apartment, even though the listing states there is, so feeding our baby was extremely difficult. The use of space in the apartment is also not great, so we felt unnecessarily cramped during our stay.
We still made the best of our holiday and had a great time in Arenal and would like to revisit one day, but there are a list of things that need to be addressed in this property.
