David is a great host, friendly and accommodating.
He contacted me the day before to ensure everything is still on schedule. When we arrived at the apartment address, David was already there to greet us.
The apartment is 5 minutes walk from Puerta de Atocha train station from the side exit gate, from the main exit it will be 9 minutes and close to Palos de la Frontera Metro station which is 6 minutes away. The apartment had everything as described, speedy wifi, towel for each guest, workable air conditioning unit in each room. It has a safe deposit however it was faulty and due for repair so we didn't use it. Copies of local maps were available in the apartment for guests to take.
There are two bathrooms, the one by the kitchen is on the smaller size in comparison but adequate. Shower gel and shampoo are available (supermarket value brand) but no hair conditioning.
Overall we had a pleasant stay for 3 nights and will definitely return if we visit Madrid again.
