1) The good:
-It's easy to contact the host through Airbnb or Whatsapp.
-2 full bedrooms and private baths, plus big couches to use as extra comfort/beds.
-Access to a spacious kitchen/dining rooms and living room.
-Comfy beds.
-Host is willing to work with you on most issues.
-Great location a few blocks near a convenient Tube (subway) stop.
2) The issues that were out of both the host's and my control:
-Construction outside the guest bedroom and living room areas starting at 8am.
-Light in master bathroom was not working (but quickly fixed the next day!)

3) The not-good:
-Having to pick-up the key at a completely separate building several blocks away.
-Cobwebs and dust in the living room and bedroom corners.
-Stairs to bedrooms that are really unfriendly to elderly. The steps are very small and steep. The entrance is on the ground floor, however.
-The guest bathroom has a problem where the water from the shower goes everywhere. We had to resort to using towels to block the water.
Overall, you get a quality location near some good breakfast areas and transportation. Other than the steep stairs indoors, this place is good for a London trip!
