You can enjoy the run of the whole apartment in Shoreditch, just minutes away from Hoxton Sq., Brick Lane, and Columbia Road Markets. But don't take my word for it - check out these words and images: https://www.airbnb.com/locations/london/shoreditch
The apartment is a recently converted warehouse which has just been fully redecorated. There are two bedrooms and open plan living - as you can see from the photos the kitchen is nestled behind some glass partitions and there's also a space for dining and studying - in case that's what you're looking for. It's fully furnished, so you don't need to bring your own sofa.
On the bed front - there are two beds, one is real, one is a nice Muji sofa bed - very comfortable, but I couldn't specify that there were two different types in the options.
There are two bathrooms - one en suite to the master bedroom. One thing to note, the apartment is basically accessible for a wheelchair, but the en suite bathroom is up one step, and the shower is up another step in there. The other bathroom (which has a bath tub) is accesible. Hope this makes sense.
Wifi is provided and there are full cooking and washing facilities (including dishwasher and washing machine).
The area is extremely well serviced for all types of fun. I'm guessing if you searched this area you have a pretty good idea of what to expect - but it would include fine dining, fine drinking, fine dancing, fine shopping, and easy access. It's fine and easy.
There are numerous travel options - a bus stop right outside the door to take you into central London or down to the City, and there's the east london line a couple of minutes walk away. You can also pick up a Boris Bike to rent around the corner. And Old Street and Liverpool Street tubes are around 10 minutes walk away.
You also get a smashing view across east London - a really interesting panoramic. If you're staying on NYE - the fireworks are amazing!
There's loads of public transport - bus stops right outside either taking you towards the City, or the west end, or up to Dalston.
There's the overground train (east London line) that will zoom you down to Brick Lane and beyond, or up to Highbury / Islington.
And you're not far from Old St. undergound (northern line) or Liverpool St. (Circle, Metropolitan, Hammersmith & City and Central lines), as well as trains and buses to Stansted (and loads of other destinations).
All together pretty much as connected as is possible. (Not sure where the nearest heliport is mind).
