Carlos’ place in Madrid is well kept and spacious in the heart of the Lavapies district. The noise at night was not too bad, although the service trucks early in the AM could get pretty loud. The space was very clean when we arrived and there was even a complementary bottle of wine provided. We enjoyed our stay overall.
One alarming part of the Airbnb was the security. One of the balcony doors does not close properly and does not lock, so if somebody wanted to get into the apartment from the balcony it would be possible. Also, the toilet kept breaking and management took 12+ hours to fix it, but never permanently fixed it. Beware that the toilet can be temperamental.
The AC/heater system also advertised in the description did not work and was broken down. It was very cold the entire time and the small space heater they provided as replacement was not very effective. If you are sensitive to the cold, I would check with management to see if the heater has been fixed.
