I only stayed for one night before flying home, but my experience was definitely a positive one. Check in was easy, and my room was big and bright. A bit of traffic noise as I was in a room at the front of the building, but it’s Mumbai - there’s always traffic noise.
All the staff were really friendly, and the buffet breakfast was delicious. The food in the fish restaurant was excellent, but massively over priced. I ordered pomfret which is 500-600 rupees in Kerala. It was listed as “market price”, but when the bill came, I was horrified to see that I’d been charged 2,400 rupees! Always ask the price before ordering. Other than that, my stay was a very pleasant one, and I would happily recommend The International, especially if you need a place near the airport. Just 15-20 mins in an auto.
