I stayed at Sandra's place for 6 nights in November. Before arriving Sandra was very quick to answer questions and let me know best way to navigate to the apartment.
Upon arrival Sandra was there to greet us and had candles and wine prepared for us - a nice touch.
The apartment had everything we needed, towels, extra blankets, kitchen utensils, hairdryer, iron etc. The bed was comfortable and shower was very good. Overall the place was spotless.
My only suggestion would be to very tall people that as it's a loft there is slanted roof pitch and low ceilings in areas.
The apartment is close to Santa Apolonia train & metro. The metro is super easy to use or can walk to main areas/plaza in around 10-15 mins.
We thoroughly enjoyed our trip and would definitely recommend!
