Check in was smooth and efficient. We had absolutely no problems with the entire procedure and Leonardo was ready to welcome us at his apartment. Upon check in, Leonardo promptly told us everything that we needed to know about the apartment and even provided more than sufficient maps and guidebooks to aid us during our stay in Madrid. He is always readily available on whatsapp and responds extremely quick.
The apartment was extremely clean and spacious enough for 3 of us. One bedroom for two people and a very comfortable sofa bed for one. The entire apartment gave a very homely feel and it was indeed a home away from home.
Just note that the airconditioning is in the living room but it can very well be felt and comfortable in the bedroom if you kept the aircon swirched on for long enough.
If you wish to wash your clothes, there is a washer readily available for use but you'd have to bring your own soap powder, not a biggie for us because we had some on hand.
The kitchen was plentiful with condiments and necessities and Leonardo even presented us with welcome gifts of fruits and a bottle of Spanish champagne.
Overall we had a very pleasant stay and we would definitely book this apartment again if we were to ever come back to Madrid. Thank you very much Leonardo for your hospitality and your little souvenir :)
