We have just returned from an 8 day stay at this site. The Wardens are very welcoming and keep the site immaculate. The site is on several levels and  The pitches are large. We hooked up to the site TV connection and did not have any problems, we used our phones to tether our ipads to wifi and had an excellent signal.  The facilities are immaculately clean and the showers warm with plenty of hot water.  It was easy for us to take the 10 minute walk to the bus stop where there is a bus every 7 minutes into Brighton Town Centre, the public transport system in Brighton great with frequent services to many area around the City and along the coast.  The Marina is a leisurly 20 minute walk from the camp site, there is a large ASDA there and since the redevelopement of the Marina there are many more restaurants to temp you, you will also find  shops, a cinema and other entertainment venues within the area. If you are walking back to the site during darkness I would advise taking a torch for walking up the road leading to the campsite. We will return as soon as we can for another visit.
