We had a lovely 9-month stay in this apartment! Carmen was very accommodating! She met us and provided snacks, basic ingredients, and tea upon arrival and always very easy to reach via phone with any questions or concerns. The apartment is furnished with everything you could possibly need — we especially appreciated the well-stocked kitchen. The location worked great for us, definitely more residential than touristic (which we prefer). It’s about a 30 min walk to Sol, 15 min walk to the cathedral and royal palace, and 15 minute walk to several metro stations if you prefer to use public transportation. We didn’t take the bus, but there was a stop right on the street as well, along with plenty of supermarkets, banks, etc. If you’re active, it is a 2 minute walk away from the lovely Madrid Rio for running, walking, biking, etc. Overall, the space is a bit compact (though very efficient) and the water heater needs a break between showers, so use your best judgement for larger groups. However, it worked very well for my fiancé and me. We’d stay here again :)
