Although we didn't get to meet Sol we were greeted by Vivian who was lovely and showed us the lovely flat. We stayed for 4 days and had no troubles. Although the flat is on the top level with no lifts, we didnt mind as this was our way of equalising all the food we ate and the view from the balcony of the church and street at this level was worth it :) The flat was accessible by the metro from the airport and is in a great location. The streets around the flat felt safe. Would highly recommend this place and would definitely stay again if in Madrid.
