Very spacious flat with all needed commodities (shower gel, towel, kitchen, fridge, TV, etc.). Perfect location in Madrid center with nearby access to all public transport.
Accommodation is managed by an "Apartment Managing Company" that is super reactive and very arranging and helpful.
One small comment : sound isolation is a bit light and you might hear some noises coming from the nearby flat.
I strongly recommend for a short or long stay with friends or family to discover Madrid 😀
