HI,
Have stayed at all Citadines property Soi 8, Soi 16 , Soi 11 and Soi 23.
They are all quite comfortable and a pleasant stroll from the action. all down a straight road off Sukhumvit which i don't mind.
Room facilities are good with fridge, jug, cooker etc. bed and air con good. gym and pool not so great but it is there.
sorry i can't answer your question as I usually play away on their property.
Hope you enjoy I'll be at Soi 11 in Feb.
regards
Papadoc
