Retirement flat hunt: Marshal Green View

Last year, after selling our big house, we're now looking for a smaller, manageable flat. Marshal Green View interested kar raha hai. Brochure mein toh full power backup aur 24/7 water supply ka promise hai. But ground reality kya hai? Senior citizens ke liye full flat backup bahut zaroori hai, common area lights se kaam nahi chalega. Water pressure aur tanker dependency ka kya scene hai? Anyone living there, please share your experience.
