Eternal's place is small, but more than adequate and cosy.
It is also really clean. One of the rooms doesn't have it's own A/C, so when I was there we left the living room's A/C unit on and left the doors ajar so that some of the air could make it's way in. We weren't there in the height of summer, so it wasn't much of an issue. However it might be during the middle of summer or winter.
Having said that, the best thing about the unit is it's location. It is practically opposite the subway station and there's also a 7-Eleven alongside a handful of restaurants (very) nearby.
Would definitely recommend Eternal's place.
