Carmen was very friendly and answered any questions very quickly. We had a minor issue with a broken light which was fixed less than 12 hours after we let her know- impressive! The apartment itself was great and in a really good location from a metro stop that gets you into the city centre in around 10/15 minutes. The only slight drawback was the amount of street noise in the main master bedroom during the night which did wake us up on a few occasions. However, we had everything we needed to set a base for ourselves the 4 nights we were in Madrid and the 5 of us were very comfortable. Thanks again for having us! :)
