The hosts are two of the most lovely people I've had the pleasure of meeting - very hospitable and keen to assist in making your stay the best it can be.
The apt is great, good size, super stylish, easy to get around Madrid.
Location is in a a bit of a quieter neighborhood but that's not a bad thing!
Only one element to factor in is that it's on the 4th floor which can be quite exhausting when doing multiple times on a daily basis.
