We had a family holiday here with 2 adults, 2 teenagers (who surf), a toddler and a baby.
Porthtowan is a nice, quiet little village. It's all about the beach, which is great, not too busy with some decent surf. There is a strong rip current but there was excellent lifeguard cover when we were there.
If Porthtowan is what you are looking for then this is a nice little house for a family or 4 adults. Overall, the house is quite compact, as per the design of most modern houses. The living room space is quite good with seating for 6 but the kitchen/diner is a bit tight. There are 2 okay size bedrooms and the bunk bed room is fine for little ones. There was a travel cot and toddler booster chair available, which were very useful.
The back garden is fairly small and is open to neighbours on one side, has a picnic table and is nice and safe for little ones.
The house has SMART TV and WiFi, which were great. Just make sure you have the WiFi code before you get there (it wasn't in the arrival book, so I had to use the payphone to call the housekeeper to get it).
On arrival the house was neat and tidy (although not quite as clean as we would have expected for the price we were paying) with good quality linen on the beds. There were a couple of kitchen items missing, which were not able to be replaced during our stay, but there was enough equipment to cater for our family, plus a few friends who visited for the day.
Overall, it was a nice holiday and the location so close to the beach made this house worthwhile, although for the price in high season it could perhaps benefit from a bit of an update in the kitchen with some higher quality appliances and a bit more attention to detail.
