We stayed in the flat for a week and it had a good location, close to the beach, public transport, handy shops and a supermarket and a handful of restaurant and cafes.
The lift to the 6th floor apartment was broken, but we where notified about this before we have checked in, and it wasn't a problem. The reward was a good view from a terrace facing 3 sides of the building, including a sea peaking put from between the buildings.
The roof terrace cover was also broken, but we where also notified and the host provided us with a sun parasol after we've asked it, it was there when we arrived. It also had air con which helped with the heat.
The flat was very well equipped - all kitchen essentials, including a water filter, and some food. It also had a plethora of blankets, bed sheets and even some fun things such as a small beach ball and other beach toys for children.
It was quite on the 6th floor, but a bit lively during the weekend, but it didn't keep us up at night.
We never met Lynne, but she send over a key hander who provided us with some helpful tips regarding our stay. She was also very quick to respond to any communication from us.
I'd stay at the flat once again, and I'd recommend it to anyone staying in Valencia including families with children.
