Jesus is a really nice guy who met us to explain and show us the apt. The apt itself was as pictured in the listing. Pretty comfortable for a few days in Madrid and in a cool location.
However, the cons:
A major problem we had was the VERY LOUD construction happening literally in front of our apt. They seemed to be jack hammering the walkway in front, starting at 7:30am, and it was very very loud, so much so I got a headache. Unfortunately the apt would've gotten a better review if it weren't for that. Hopefully that will be resolved for the next tenant, because it is unbearable.
Also the parking was a bit confusing because it is listed as free on premise parking, however it is actually 18$ a day. Which is listed on a picture very small, to be fair.
Overall, if it weren't for the construction, the apt is quiet and comfortable. Jesus is very accommodating and even gave us a free day of parking. I'd recommend the apt, once the construction is done.
