This was a perfect spot slightly off the tourist route. It was a great place to stay on my last night in Spain. And very easy to hail a taxi to get to the airport. I would definitely stay again.
Just a notice to future guests: The elevator is not on the basement floor, it's on the 2nd floor. This was shared in the check-in detail after I reserved the apartment. And even when you get off the elevator, you still have to go up or down a small flight of stairs to get to the actual apartment. This posed an issue for me getting my 50 lb/22.7 kilo suitcase up and down the stairs. If you're packing light, then it's no big deal.
