We stayed 3 nights at Cordia Residence Sathorn from 24 - 27 Dec 2016. This hotel is very, very basic. Not ideal for family or couples. But for single travelers who don't want any frills, need a place just to house the luggage and sleep at night, Cordia Residence Sathorn is great value for money (I paid about S$30 for a room per night). It is located at the entrance of a small lane (Sathorn Soi 8) so taxi drivers may not know where it is. We used Google maps to direct the cab driver to it.
You'll get a local feel staying here as during weekdays, workers from surrounding offices come to a few food stalls around the area for lunch. The nearest BTS station is Chong Nonsi, which is about a 3-minute walk away. The whole hotel looks aged and there's a musky smell but for that price, can't really ask for much.
The worst room to stay is room no. 205. It is right next to the lift so you can hear other guests pass your room and it is the smallest. We booked 3 rooms and although I paid the same price for all rooms, no. 205 is the smallest. After I put my luggage, there's hardly any space to walk. And it is also just above the small road so you can hear traffic. The water heater also wasn't working. Indicate in our booking NOT TO STAY IN ROOM 205. That is if the staff understands what you wrote as English is not very understood in this hotel.
