The location of the apartment is perfect. It is close to trains, the metro, parks and the amazing food and nightlife of Madrid. We were there as a family of 5 and the apartment was accommodating for everyone while still maintaining a decent degree of privacy.
The kitchen, while small (accurately reflected in the pictures) was well stocked and could have easily served to prepare far more complex outings than the simple breakfasts we used it for. But why would I want to cook in central Madrid. The quality and breadth of food available within a few minutes walk in any direction from the apartment is amazing.
The bathroom is a bit small but no more so than an apartment of this size in New York or any other large city. The pictures are all accurate so no surprises.
The beds were all comfortable and none of my party complained (which is strange). The balcony out front on the street is mostly protected from direct sun so the place does not get overly hot inside during the day and with the fans that are there used at night, it is still quite comfortable to sleep.
The communication and response times to questions from Stephanie were excellent. The first day we noticed there was no coffee maker. We politely asked about it and her response was almost immediate. She ordered one and had it delivered the next morning. I also had various questions about the area itself as I had never stayed in that part of Madrid. All of here answers were spot on and saved me hours of research and a lot of legwork.
The apartment was spotless when we arrived and she had left us a little welcome gift as well that was much appreciated by all. The apartment was also well stocked with cleaning supplies as well. The presence of the clothes washer was also a definite plus.
Overall, I would say that all members of our party had a wonderful time in Madrid and it was made better staying at Stephanie's apartment. The location of the place and the communication with her throughout our stay all added to the experience and made the week a memorable time for everyone.
