We had a great stay at Oscar’s place and found the Airbnb to be in an amazing location and easy to get to by metro and taxi. Oscar greeted us later in the evening which we were grateful for, and also allowed us a later check out which was helpful. The Airbnb is decorated beautifully with everything you would need, including slippers and other hotel-like treats which was a lovely touch. This was our misunderstanding but the locked entry-way is for 2 apartments so we initially left the connecting door opened and was startled to bump into the neighbours, so worth noting to shut this door!
The Airbnb is located on a main street so is quite busy and loud outside but that was fine for us as we had late nights out anyway. As a few other reviews have mentioned there are female entrepreneurs working in the building but this isn’t problematic at all and they keep to themselves. We would definitely visit Oscar’s apartments again if visiting Madrid!
