If you are looking for a clean budget accommodation in Guangzhou, I would recommend Guangzhou Youth Hostel. They are not just clean, decent and reasonably priced, it's also strategically located near to the subway station, peaceful with beautiful scenery facing the river where you can take the ferry to cross the river at only 1 yuan per trip. And the ferry service is so frequent. There is also a park nearby where you can see lots of local people especially the elderly exercising during the evening and morning.
And the train at the subway is also very frequent, and you don't have to rush for them every time you are there. If you missed one, another will be coming by in just a few minutes. And the trains can take you to most of the popular tourist spot. And in Guangzhou, I prefer to travel by metro train as they are clean and efficient.
And during my free time I like to sit by the river be it during the day or night time. Both have different feel. I especially like to watch the sunset at the pier, and feel the lovely wind blowing during the night. Standing by the river watching tall buildings with neon light remind me of my Shanghai trip at The Bund.
The hostel not only provide free wifi service at the lobby, they also provide 3 stars bed rooms. And they use card system as lock. And the only problem I faced during my stay is they don't have any tourist friendly restaurants or stalls around, unless you speak Cantonese or mandarin. But if you enjoy drinking. the beer street is just next door. There are lots of KTV lounge, pubs and night clubs all along the street.
