Splendid location in Las Letras close to the Anton Martín metro station.
Superb tastefully furnished apartment; you really feel at home instantly --Neflix was appreciated to see some Halloween specials from the comfy sofa--, comfortable bed, well furnished kitchen, washing machine, ironing board, and a lot of nice touches from Alexander (a fridge stocked with fresh fruit and soft drinks. What more would you want?
Alexander also was a great help throughout the stay, responding promptly on any query on via private Whatsa**, and with impeccable advice about e.g. vegetarian-friendly restaurants to visit.
