I needed an accomodation close to the DLR, a few minutes from the airport, and Appartello was a very good choice. Very close, at a reasonable price. I only needed a night, and Appartello, as far as I understood, was more meant to be a long-staying place, in fact it looks a lot like a small apartement, very large room and Bathroom, it has a microwave oven and a minibar (only water in it, so it's basically empty and you can fill it the way you prefer). The room was new and very clean, there's a nice wall mounted flat TV with SKY sports for free, for those who are interested.
Baggage deposit available, and personnel very friendly.
Also the breakfast was available for like 9.99€ (continental) or pay-what-you-eat like, with coffee free.
