Can  you help me find a place to stay that's four stars and has free wifi? 
Twenty one accomodations meet your needs. What part of town are you planning to stay in?
That doesn't matter as long as it's cheap.
There are 21 places in that criteria. What area of town? Or perhaps a need for free parking?
It doesn't matter. Like I told you, it just needs to be a cheap 4 star place with free wifi.
The Alexander bed and breakfast is the best option.
