Great location right on the heart of Madrid near Sol train station. We caught the metro from airport and had to swap 2 lines but it was easy. Caught pink number 8 then swapped to dark blue number 10 and then swapped to yellow number 3 to Sol. Great newly renovated apartment with washing machine/dryer, dishwasher and kitchen. Felt very secure and only had 2 flights of stairs. Beds are good and photos shown are accurate. Mast was very friendly and helped out with any request required. Fridge even had a cold beer and some soft drinks. Kitchen had some basic supplies of oil, salt etc required for cooking.
Bathroom had some basic supplies as well. Highly recommend to due apartment quality and location.
