Stayed here for two nights on a stopover. 7 Days Inn is very much a budget formula but nevertheless it is not particularly cheap. The room was basic, but clean. WiFi worked. There is not much else really, a cramped lobby with a vending machine for snacks and water.
I stayed here in Oct 2011 in between of visiting Qumarleb and my uncle's place. Price was reasonable, pretty easy access by mass transportation. The building was an old one but inside was neat. Guest rooms upstairs were better an warmer than those on the first floor.
