Location was perfect for us...close to the train station, easy walking to historic and shopping districts, and in a vibrant neighborhood with local shops and markets. The large windows overlooking the terrace provided great light all day long and even though we were on a busy street the multi-paned windows kept the apt. quiet.
The best surprise was how well equipped the kitchen was. We ate breakfast and dinner in the apt. during our entire week stay and really enjoyed the abundance of dishes, utensils, appliances, good counter space and room for several of us to be in the kitchen at the same time.
Our stay at Joanna's place was great and I highly recommend them if you are planning a trip to Madrid.
