This a wonderful place to stay - it has everything. The apartment was clean and stylist, beds were comfortable, no issue with noise, air conditioner worked great (we like it cold at night), hot water for 5 adults, washer and dryer that were very easy to use. Also, they were great with allowing us to leave our luggage for a few extra hours after check out.
The location is amazing. You are a block from the metro, 1 1/2 block from the palace, a few blocks from Plaza Mayor, and a few blocks from San Gines chocolatier. There are markets close by for water, fruit, snacks and drinks. There are also so many restaurant choices in each direction. If ever back in Madrid, we will be staying here. We loved our stay.
