Everything fine in general: great location for Liverpool St / Spitalfields / Brick Lane areas, but of course it's very busy and quite noisy, so maybe not ideal for a family. As a couple of guys in London for work for a few days, it was fine.
The apartment is spacious, functional and clearly well-used for passing through travellers. Only issue experienced was WiFi, as we had to use the open signal from a nearby business since there is none in the apartment.
