We had a wonderful stay at Laurel's apartment. The place is very conveniently located. We walked from Cibeles where the shuttle bus to the airport arrives and that takes about 15 minutes. Laurel showed us around and was very welcoming. The place is small but cosy and has a nice shower and kitchen. It's also close to all the important museums and squares of the city. An added bonus are the many restaurants in the neighbourhood and the wonderful Santa Anna square which is just around the corner. Definitely worth checking out if you are going to Madrid!
