This place is amazing, if you want to be in Madrid DownTown, this is your place. Very comfortable, convenient, and has everything you need. Fes steps away from Plaza del Sol which has access to everything.
One thing I'll advise is that it is on the 4th floor with no elevator, so children, the elderly, or people with limitations could encounter difficulties. Also, the area is active so there is some noise and activity going on until late, nonetheless, the place is well isolated, but is important to consider for small children or people with light sleep.
Besides that, it is an incredible place to go and visit Madrid.
