I have booked a flat in Mayur serenity. Its been more than 5 years now but still the flats under construction. These guys are extremely evasive builder and trying to loot our hard earned money by playing politics between partners.
Please avoid this builder. I would highly recommend not to pay any money till possession. Do not trust them. If you have doubts.
You could visit their own website Mayur-Group.in for progress photos, you would find the same photos for the past few years. They might take out the pictures from their website if someone from their group reads this review.
