We had a great stay in Madrid.
The flat is located in the middle of the city with all the restaurants and sights around it.
The public transport is so easy from the airport too and the penthouse flat is great.
The only thing I would say is there were no English Channel on tv (fair enough is Madrid) but I would recommend to upgrade the tv to a smart Tv so ppl could connect to the WiFi and watch other languages too.
Overall it was great still 5 star! Well done guys
