This location is extremely convenient getting on/off the tube via Warwick Avenue station, extremely close walking distance. The Little Venice area is very quaint, lovely walking path along the water with lots of great restaurants in the area.
We had plenty of room for 9 guests (7 adults and 2 smaller children). I would say the most challenging part of that number of people in this space is sharing two bathrooms. We found that only one shower could be used at a time (not enough water pressure if running two at the same time).
Check in/out was extremely easy. The location was easy to find. Beds were comfortable. The winding staircase +kitchen floor (level 2) is a little worrisome with small children, elderly, or someone with mobility issues. Children require constant oversight in this area of the home.
Overall, lovely stay with some maintenance issues to share privately with owner.
