We stayed for a week in this flat and we enjoyed it. The location in chueca is super nice and the flat is perfect for a couple. you can always catch the sun from the balcony and the living room is great.
We don't recommand the flat for more than 2 tho, because the couch is super thin and not particulary comfortable.
The flat is well equiped but you will need to buy everything if you want to cook (only salt for us) We left some dry non-perishable food, maybe the start of a thing..
The flat is owned and handled by agency so its not a classic airbnb experience but we gave 5 stars because this a great deal in Madrid and the flat is nice and well-placed.
