This location is AWESOME! Great location value for the price. I wasn't expecting such a tight space, however, and it wasn't that big of a problem, just be prepared for a tiny little big-city apartment. We had three people and it felt kind of cramped, but it's definitely okay for the location and price.
Host was super easy to communicate with and gave good recommendations for places to eat and shop nearby. Lots of great Tapas places nearby and a coffee shop right across the street.
Our only complaint was the amenities of the place. There wasn't a fitted sheet which made sleeping on the bed difficult as it kept coming off the mattress, the towels weren't super high-quality, and the kitchen isn't super well-stocked. So if you're planning on using the kitchen you'll need to bring your own oil, sugar, wine tool, etc.
Overall good stay!
