We loved Malena’s place - it’s conveniently located in the center of Madrid, the area is quite which is definitely a plus.
The apartment is very cosy, equipped with everything you need - appliances, all kinds of kitchen utensils, small but necessary things like salt, oil, tea etc are all there. There is a double bed (though not a big one) in one bedroom, two single beds in the other - rather small bedroom without a window, the couch in the living room can not be used as bed - so the apartment would be good for 3, max 4 people.
Communication was excellent, Malena was always in touch and very helpful. She was also understanding about our late check-in time.
There was an issue with the shower drain that unfortunately was not resolved, but other than that everything was perfect!
