We enjoyed 4 nights in this flat in December 2016 and we recommend it highly. The apartment exceeded our expectations and Raul was welcoming, had helpful tips about the area and was flexible about our departure time. Although the building is old it has charm and there was a modern elevator which left only maybe 6-8 steps up to the 4th floor flat. It is an older flat but it was clean, well appointed, quiet during day and night, and decorated in a cute, arty way. The sheets, towels and mattresses were of high quality. The heat, hot water, water pressure, and washing machine all worked well. It was nice to have the bathroom plus an extra toilet and we liked the way the bedrooms are at opposite ends of the flat. The location was super - we walked easily to the Prado, Plaza Mayor, Sol, the Palacio Real, Cibeles. This flat is not flashy or 'high end' (no giant tv or nespresso machine) but it more than met our needs and we would happily return.
