I stayed at Olga's place for a weekend. It is at a great location, very close to the station and on the ground floor, which is convenient if you have heavy luggage.
There is no cooking facility other than a kettle and a microwave but you won't miss the stove as it's right next to the night market, lots of restaurants, and the MRT.
There is also a big window which gives the room great natural light during the day.
Olga is also super friendly and helpful!
