The apartment is in an excellent location to visit all the tourist spots in Madrid. It is only a short walk to the Anton Martin metro station (Line1), which can connect you to the Atocha train station and even the airport. Madrid has an excellent transportation system!
My husband and I found the apartment comfortable and roomy. It is on the 2nd floor (with elevator) and it was nice and warm. There are heaters in each bedroom and the living room. The bed was great! The wifi was a bit slow, but we were able to stream Netflix and the news on our laptop, so all good. The kitchen is a good size, fully equipped and the washing machine was very good. Showers were good - we had plenty of hot water. Vanessa is a wonderful host and very accommodating as we had an early check-in.
