Great apartment in a great neighborhood.
We stayed for five nights -- Mas met us at the tube station and escorted us the (short) walk to the apartment. It was perfect for us.
Very clean and modern with everything you'd need for your stay, including a washing machine / dryer.
We opted to not stay at a hotel because we wanted to get a real feel for the city and this place fit the bill. It's on a secluded street behind a busy street, so you get the best of both worlds -- it's quiet, but one block from every kind of restaurant or supermarket.
Also -- a great part of the city, very easy to get anywhere within about 20 minutes on the metro.
