William was a very helpful host, who came to pick us up on the way from the airport to the flat, at a very very late time (1 in the morning) to make sure we wouldn't get lost on our way there.
We had a minor issue with the brand new boiler in the bathroom and he came to look at it and tried to fix it the very next morning.
The flat is exactly as described in the ad, very spacious and sunny and very convenient too.
I would really recommend it to other travellers, however note that there is only one double bed, which might not be convenient if more than one couple stays there. But the balcony is really enjoyable, there's even a barbecue and it's close to the sea front.
