Lovely apartment, very clean, well-decorated with everything you need. The location was perfect, with close distance to Oxford street and Oxford Circus station without it being too noisy. There were also lots of nice restaurants around the area and Sainsbury's, Co-op AND Tesco within 5 minutes of walking distance! Hosts were quick at replying, though I didn't get to meet them because I arrived at the apartment later than the rest of my family.
The only drawback would be that it's on the top floor (3rd floor) with no lifts, so it was quite an effort to carry our bags up and down the staircase.
