VanZyl's flat is truly amazing, it is exactly the same, or say, even better than the pictures showed.
The location is quite good, 9-10 minutes walking to Vauxhall station, where it has all the tubes, trains, and many buses that can lead you to basically most places in London. There are several small stores within 2 minutes of walking. Also, there are bus 77, 344 and 360 within 5 minutes walking that can take you to the Vauxhall station.
The decoration and environment of the flat are perfect, it is in a very secure building with a reception (although not 24h but still quite good), the underground heating system is also quite effective, you can feel the flat became quite warm within 1 hour. Kitchen has almost everything, from the washing machine, dishwasher to all the essential tableware, and a lovely toaster.
Cleanliness is always what we care about the most, and it was perfect. All the beddings, towels and other stuff all are clean and very tidy.
Personal check-in was quite smooth and effective, I am very grateful that Mariusz introduced to us all the rules and facilities of the flat, which is quite helpful. You can also see the views of the Thames on the lovely balcony.
In all, it is such a wonderful stay and the price is fair for this environment and facilities. We will choose to stay at this one if we ever visit London again, and we highly recommend this to a 2-3 group of people!
