Great location - the house is easy to find and is just minutes away from Waterloo station. The house is well maintained, the amenities all work and are very good. The bathrooms are clean and well supplied. The kitchen is well equipped and functional - we cooked every day and ate at the dining table. The washing machine and dish washer are in good shape. There's free wifi for internet access and lots of channels on the TV. The bedrooms are comfortable. We stayed for nine days and enjoyed every bit of it.
Housekeeping (cleaning, change of linen, resupply of bathrooms) is not included in the rent and should be separately requested for and scheduled.
One point to note and plan for: late checkout is not really an option, and there isn't a left luggage facility. It just isn't practical. Therefore, if you have a late flight on your checkout date, simply pack and leave your bags at the nearby Waterloo station's left luggage facility while you walk about.
We loved the place and think we have found our vacation home at London. We will be back!
