The apartment is really nice and well located.
When we arrived, there was a problem with warm water, the host tried to help but it took 5 days to fix it. They reimbursed us 2 days.
At night, Fuencarral can be very noisy.
We stayed one month and we were told that the extra charges were about 50euros. At check out, the host asked us 157euros (according to the estimation). We asked the host to double check the actual costs once she received the bills as we almost never used the heater. She agreed and we are waiting for her to let us know.
