Great apartment in a great location. Paula and her team were really responsive (and friendly) and made sure I had what I needed (like cleaning supplies, new sheets/towels, etc.) to make it work over several weeks. The location is a plus: close to Atocha, the Prado, Thyssen, Reina Sofia, the Retiro, the metro, great restaurants, etc. The neighborhood is active during the day and (for the most part) quiet at night since it's not super touristy in Las Letras. I stayed here as a solo female traveler for about a month and it always felt safe, which is important. I was working remotely and the wifi was sufficient for that.
