I flew BOM-BRU-BOM in 9W J class last Jan, so it's been some time. I found the graveyard configuration quite uncomfortable. My seat was Aisle in the last row (I think 8) and it was difficult to sleep. Try to take 1A or 1K - those are probably the best seats. Ajay has a posted a good review in past.
Having said that, the service and food was decent and I have no complaints on these fronts.
