We truly enjoyed our stay at Melvin's apartment. It was very clean and very well located. The location was close to Grand Vin (about 1 block), making it very easy to make excursions to major sights and shopping venues in Madrid. Elevator access made it easy to move luggages around. My wife and our 4 years old felt safe in and around the vicinity during our stay. On top of that, Melvin and his staff made it very welcoming for our stay. He proactively checked on us to ensure our arrival was smooth, and offered us help if any was needed. Also his office located about 200m away provided early luggage hold and post checkout luggage hold. The taxi driver he hired for us was very convenient; he waited for us outside the office where we left our luggages at on the scheduled time, and cost just as much as the regular taxi would have costed us (30 euros flat to the airport) Melvin was always responsive to any messages on the app. Thank you again.
