This place is fantastic. Location is perfect - close to the underground, the british museum, oxford circle, lamb's conduit, restaurants and pubs. I stayed alone but it would be perfect for a couple looking for a luxurious spot with plenty of space at a great price. You can't beat this price for this area. Christian is always available and very communicative.
One call out to my North American visitors, the place has plenty of converters for your electronics. The kitchen is really nice and equipped if you're looking to cook or just make morning coffee. The bed is incredibly comfortable... I can't say this enough; a really good mattress.
Also, go to the bookstore below the flat and the coffee show next door. Really unique spots.
