This apartment was perfect for my travels (solo traveller on holidays in London). The place was extremely well stocked with amenities, with everything in working order; and it is in a great location. There is a local Tesco just 2 mins down the street and ample transport within the same distance to go around London. Van was always fast to reply to messages, which was incredibly helpful, giving detailed information when needed.
I would recommend this apartment for solo travellers, couples, or groups no bigger than 3 (as there isn't a lot of storage space for big luggages). Another thing to note when booking is that the mezzanine bedroom is rather high and so is quite close to the ceiling, and may be difficult for someone older to duck in. There is enough space to sit up when on the bed (I'm about 173cm and still had a little bit of space above my head).
But, other than that the place was incredible and furnished with lots of books, dvds, and a working piano to keep you occupied if you don't feel like exploring!
