We were a group of 11 consisting of two families, each including three generations, and each from a different nationality. It was a challenging gathering from the get-go. When we got to Malta we immediately encountered a major snag: the two rental cars we reserved were not available.
Arriving at the villa without proper transportation was a big nuisance. Luckily, Karen was very understanding and helpful, and drove us to the local supermarket (3 minutes away by car), and after we finished shopping she drove us back to the villa.
After the issue of rental cars was not resolved on the second day Karen helped arrange a rental car which arrived on the morning of the third day, after which our vacation could really begin. Karen was a great host who helped us with all our questions, explained the ins and outs of the villa, suggested restaurants and helped arrange transportation back to the airport, and was very responsive when questions came up.
About the villa itself, it was very spacious and convenient, the description of the villa was quite accurate. There are great amenities like smart tv, washing machine, large area to hang laundry, big stove, barbecue pit, etc. We were a bit worried though about the pool not being fenced, and therefore a danger to unsupervised children playing in the yard. We wish that the pool had been heated, since in April it is still too cold to use, but we understand this would have made the place much more expensive, and we had plenty to do in Malta besides. Note that the villa is in a quiet neighborhood of villas, and a strenuous walk from any points of interest, which makes it difficult to use without having vehicles.
There were some issues like the internet being wonky every now and then, and the garbage not being collected on time, but these are probably issues that cannot be controlled by the host.
The villa was a huge success in terms of accommodating our two families, and we were very comfortable, and even with one bedroom to spare, which was used to "divide and conquer" the children during bedtime.
All in all we highly recommend sunny side villa, and recommend to ask Karen for help arranging for things in Malta (before arriving), as she has proved to be quite reliable and helpful.
