This place was amazing! Very modern, very clean.
The space is small but as a four persons group we never felt oppressed by it.
The appartement is very well located and since it’s not directly on the street, you can’t here any noise throughout both day and night (which is a big plus in madrid).
It is very well equipped and the host puts so many little things at the disposal (from shower gel and shampoo to kitchen things like sugar, coffee, marmelade, butter, etc.)
As you may guess from my comment I really recommend this Airbnb!
