What a great experience! The flat is perfectly located in one of the city's coolest neighborhoods and has everything you need. We really appreciated all the little touches such as the coffee and milk, shampoo and body cream, snacks, etc. Unfortunately we didn't manage to enjoy the bottle of wine that was left for us, but maybe next time!
Conchita and Jose were also both lovely and we appreciated them taking the time to greet us and give us a list of suggestions of places to go/things to see (which were all excellent!). We would definitely stay again on our next trip to Madrid and highly recommend it!
