Loved our room at Colorz Hostel. It was more spacious than most guesthouse rooms in Hong Kong (my husband and I stayed at the standard double room) , and looked very well maintained. Our room was cleaned everyday, and we had a change of towels daily too. Bed was comfortable, hot and cold shower was working well. There was free and fast wifi, and check in was easy. If you're taking the A21 bus from the airport, simply get off at the Mody Road stop. Union Mansion (where the hostel is) is right on that block. Best to save Union Mansion on Google Maps beforehand so you wont have trouble finding it (if you get off at Mody Road stop, the entrance to Union Mansion is less than 50 steps away). Nearest MTR entrance is P3 (East Tsim Sha Tsui). Excellent location and service! Would stay here again.
