This was exactly as described. It would be perfect for a couple but was absolutely fine for the four of us that stayed. The location was very peaceful, the kitchen was well equipped, the sofa bed (which I can personally vouch for) was super-comfortable and it had a good shower. The walk to the nearest metro was about 10-15 minute through a quiet neighbourhood and then it was only 3-4 stops to the Capitol Hill which was great.
All communications were very clear. I recommend!
