I stayed in this apartment in June when the weather was hot in the 98-101 degree F range. I met Fedi who briefed me on his place. He also provided a 2 page cheat sheet on the apartment which included recommendations on places to eat in the neighborhood. The apartment is located in a very central location right off of Gran Via and a 2 minute walk from the Gran Via metro station. It took me about 50 minutes to get from the airport T4 metro station to the apartment using the metro. There are Carrefour Express and El Cortes Engles basement supermercados conveniently located nearby heading toward Plaza del Sol. Calle del Desengano which the apartment faced looked sketchy at first with some street walkers but I felt safe walking to and from the apartment. Security was excellent with 3 locked doors that you had to pass through to get inside the apartment. The unit was larger than expected and looked just like the posted photos. The bed was comfortable and there was consistent hot water for the shower/tub. The wi-fi was consistent and fast throughout. The kitchen was well equipped with a refrigerator, 3 electric burners, sink, microwave, toaster and washer. There are some clothes lines in the interior courtyard which the bedroom faces for drying clothes.
The only issue that I had was that the portable air conditioning unit located in the living room could provide cooled air only if the rear hot air exhaust hose could be blown out of an exterior window. Since there is no window available, then the air conditioning unit for cooling was essentially useless and just became a recirculating fan. That made for uncomfortable hot interior temperatures of 80-83 degrees even with the windows open at night. With the windows open, you can also hear the daily trash truck stop by in front at 2:30am and the kids partying in the streets till 6am.
Overall, I would recommend this apartment for its central location, large size, complete amenities and reasonable rates during cooler weather. I would select another place with effective cool air conditioning during warmer weather like what I experienced during my visit.
