Which is the better hostel in terms of location and ambiance? UDEE BANGKOK (Pradiphat Soi 19,Samsennai, Payathai) OR BANGKOK CENTER SUKHUMVIT 25 (Sukumvit Road)?

We would like to do cheap shopping, sightseeing, going to the lying Golden Buddha, Chatuchak market, night markets, Patpong, etc. Anything else we can do on our 4-days?

Can anyone recommend an itinerary?

Thanks!
