Overall, the apartment is cozy, the location is great, and I would considering staying here again. With that said, a few pro (+), con (-), neutral (=) points:
=: first impression. Apartment (#7) was a bit different than shown in the photos. (the kitchen layout, bedding, living room furnishings, etc. were different) and it was a bit dated in some areas
=: we were told the taxi driver had our keys; however, we arrived and were greeted by someone at the building who seemed to have our keys. This was confusing.
+: everyone was very friendly, accommodating and responsive
+: the bed spaces and comfort. We enjoyed that everyone could have their own bed and slept well
+: the kitchen was sufficiently stocked; however, the knives need sharpened
- : homeless people loitering in the front entrance during an event in Soho Square. 2 blocked the building entrance Saturday night and another one was openly using an IV needle. None were confrontational or aggressive, but this caused some personal unease in case of unpredictable behavior and traveling with 2 youths
+: the building is very secure and entry is limited, which offers some peace of mind considering the above.
+: the location is very good! There are shops, food, and tube stations all nearby. Leicester Square is very close for walking to.
