The location of this place is great! Metro, Atocha, museums, restaurants, are all close. Also, UNILAB, where you can get your COVID-19 test is a 15 minute taxi from the flat. The apartment is a great space for two people on a short visit or backpackers. Although it is on the first floor the windows minimize the noise. Javier was very accommodating during the check-in process as well. I would stay here again.
