yeah, I'm also looking for a place to stay. I don't like hotels, so a guesthouse would be better. Moderate in price.
There are several moderate priced guesthouses do you  have a preferred area that you want to stay in?
Yes, the hotel should be in the east and doesn't need to have free parking.
a and b guest house is a guesthouse in the east and it is moderate. Shall I book it ?

The star rating is 4 and they do have free wifi.
