This apartment has what you need and the hosts (I was in constant communication with Elizabeth) are extremely responsive and problem solving, despite of the distance and time difference.
I felt absolutely safe in this space. There is security 24/7. It is pretty quiet.
The neighborhood is amazing. It has a lot of restaurants and if you like to walk, you can go to the “Angel de la Independencia” in 21 minutes or to “Fuente de Cibeles” in 15 minutes. If not, just take Uber and it will get there in less than 5 minutes. In both places (Angel and Cibeles) you can take the Turibus, which is a hop on/hop off system that can take you to the most highlighted areas of the City. There are additional public transportation methods accessible and really closed to the apartment. I stayed there fo 2.5 days and was able to do a lot of things thanks to the location. Location is everything!
If you are looking for a beautiful, cheap and safe place, this is the one.
