This flat is a study in extreme minimalism. If you like minimalism, then you'll find things to like in this flat. It contains the absolute bare minimum of the things you'll likely need, and pretty much nothing more. In terms of just comfort, there is nothing besides a bed (while of course you can sit in the chairs and sofa, both hard and uncomfortable - they are not places to rest or relax).
The furniture is very basic - besides a double bed (just double, not queen or king), there is a chest of drawers, a bookshelf, a small (very small) dining table, an even smaller coffee table, two outdoor (plastic) chairs and one 2-seater (barely) sofa devoid of cushions and that seems to also be outdoor furniture. Most notable is that the only - really the only - decoration in this flat is one vase-like ceramic piece on the windowsill. There is nothing on the walls, nothing on the bookshelves, nothing in or on the chest of drawers. To emphasize this minimalism, the floor is wood stripped almost bare - as if it's still waiting for the flooring to be finished. There is one rug that covers part of this wood flooring, but otherwise it's all exposed, nails, wood imperfections, and all. There is a small room-divider that is placed close to the alcove where the bed is located. I wasn't sure if the purpose of this divider was to block sunlight from the window or to block the sound of passing traffic. It seemed to help at least a bit with both. Finally, there is an odd metal structure - a thin metal bar on metal supports - that seems to be meant for hanging clothes on - but there are no hangers (see above about extreme minimalism) so it's unclear how it's meant to be used apart from just throwing clothes on it directly.
This flat is in a central London neighborhood very convenient to lots of other places in London (there are several nearby Tube stations - Euston Station, Euston Square, Russell Square) and even convenient for places outside London (there are two nearby train stations, Euston and King's Cross), and there are a variety of restaurants and small grocery stores nearby. There are also several universities nearby. But the flat is located on a very busy street - there is a constant sound of passing traffic and sirens. I slept with ear plugs - those together with the small room divider made it possible for me to sleep in spite of the traffic sounds. In cooler weather when the windows could remain closed this was bearable. It would bee unbearable in warmer weather when the windows would otherwise need to be open.
The kitchen is sparsely equipped - a small number of large and small plates, four small bowls, two glasses, four small mugs, a bit of silverware, a bottle opener (but no other utensils as far as I could tell), a kettle ( but no coffee maker), and one wok. There is a sink, a small fridge, a microwave, and, surprisingly, a more-or-less normal size cooker. That is pretty much all there is in the kitchen.
The bathroom was fine - it's much larger than the kitchen - there's an electric shower that you have to figure out where to turn on (hint: the switch is not in the bathroom). There is a washing machine (I didn't need to use it) but no dryer. There isn't really any place to dry clothes beyond the towel rack in the bathroom and that strange metal bar in the main room.
If you are looking for an inexpensive place to stay in this area of London and you don't mind extreme minimalism, this is probably a good choice for you.
