We were a family of 5 adults and our stay was perfect. Location is really, really good. In Zone 1, less than 10 min walk to Angel tube, where several grocery stores, restaurants, coffee shops, shopping, and pubs are close by. Less than 15 mins walk in opposite direction is Kings Cross/St. Pancras. And less than 5 mins to a couple bus lines that take you anywhere into the city. Between us we used Apple and Google maps and citymapper app to get all over. We couldn't get cab app to work as we didn't have a credit card tied to a UK address. But was easy to get an Uber a couple times once we got the app to work.
Comfortable beds, very comfortable for 5 adults (I think 6 might have been pushing it - the 3rd bedroom was just fine for 1 person but would have been a squish if we had a 6th person).
Kitchen stocked well enough to prep easy meals.
Outside sitting roof terrace area just off the sitting room was really nice.
It was super hot when we visited (in the upper 80s, almost 90 degree fahrenheit), but cooled off enough at night to be able to sleep.
