Javi's place is situated in a very accessible area, the place is nice and clean and is perfect for a few days in Madrid.
The host was not as prompt in replying as we were expecting, but he was nice to let us in before the check in hour to leave our luggage.
The apartment is equipped with everything you need for a few days, but it was a bit cold so we had to use the electric heater which I wouldn't say it was enough.
We had issues with the hot water in the shower which was over until the 3rd of us could use it, so we had to wait for the boiler to heat the water again.
Overall, it was a nice experience, but the place could you some improvements.
