I stayed for 6 nights in this apartment, which was located in a very safe neighborhood. It was a 5 minute walk from Sagrada Familia and had many good dining options nearby. Two different Metro stops were less than a five minute walk away as well. Check in was easy- the virtual keys I was provided worked throughout my stay.. Lots of stairs to get from the building entrance to the apartment. It is technically a second floor apartment, which means it is a third floor apartment by American standards- six flights of stairs to climb. There is a small elevator which can fit 2-3 people at one time. The apartment was generally clean. I noticed a broken doorknob for the bathroom, which could lead to someone getting locked in. The three bedrooms all came with linens and were generally comfortable. The owner was very responsive to all the questions that I had. All in all, this was a nice and safe apartment to stay in. I would make the following suggestions to the owner in order to improve the experience:1) Coffee, Coffee Filters, Cooking Spray, extra garbage bags, toilet paper and cleaning supplies would be very helpful to have in the apartment. I spent quite a bit of time obtaining these products at supermarkets. These little things would have made my stay more enjoyable.2) The washer and dryer either did not work or we could not figure out how to get it to work. The owner was super responsive when I inquired about this and offered to send a maintenance person to look at it.
