Oasis Guest house is really well located, right near Chinatown, 2 minutes walk to Petalling street market and Pesar Seni station. The room is ok, no outside window but one on the corridor so the room is a bit dark. All the common areas are smoking, even the kitchen where you take breakfast. So if smoke bothers you, you will be annoyed as several people gather there to smoke as it's forbidden in rooms and dorms. Kitchen area and crockery are old and look dirty. Finally, don't take a room on the 1st floor near the front desk : the man at the front desk at night listen music, and we asked him twice to stop the music as we could not sleep, he didn't stop it, arguing he get bored without it!!! I would not chose this hotel next time.
