Highly recommend - Ramon is super communicative and accommodating and this place is in an absolutely fantastic location. Walkable to the city center and near multiple public transport options, the apartment is very easy to get to from the airport or Atocha RENFE station.
The building is very safe and the apartment itself is very chic and clean. The kitchen is well stocked with cutlery, flatware, appliances, and a washing machine. There was however no laundry soap/detergent or microwave, so keep this in mind if you plan on using either of those facilities.
One thing to note is that the apartment is on the ground floor so the windows/terraces in the main bedroom open to the just above the street level (not so great for privacy). Additionally, there is limited hot water so if you are not traveling alone keep this in mind as it takes about half an hour for the hot water to return.
