Had a great stay at Red by Sirocco, the room was very spacious and comfortable to stay in. The bathroom was very nice also.
The location of this hotel is quite close to Dang Wangi station (about a 5 minute walk), though we found ourselves taking a Grab more often than not. There were a nice street of great dining options leading to a big mall (opposite the Sheraton) less than 5 minutes on foot.
Being 2 female travellers we didn't feel entirely comfortable going about the alleyways around this property at night. We made sure to stick to main roads and to take grabs if we were coming back later in the night.
The breakfast buffet was quite good, inclusive of an omelette bar, a nasi lemak station, other hot foods (that weren't actually kept hot...), breads and pastries, and fresh fruits and vegetables. On the rooftop level overlooking the infinity pool, we always started off our day well. The infinity pool itself was the perfect temperature for hot KL afternoons, and it's usually not crowded which is good since the pool itself is not huge.
Overall, a very nice stay with Red by Sirocco.
