Great place to stay for exploring Madrid. One of the rooms is quite small so won't fit a couple (unless you're very much newly in love :)). You can hear some neighbors every now and then but it wasn't disturbing our sleep.
We mostly used the apt as a base camp for exploring Madrid and for that it's definitely a perfect rent.
Eyal's communication was perfect and he's very quick to respond to your messages. Could not ask for a better service!
