We had a fantastic stay at Guillermo's place. It was really well located close to the subte and everything was super-clean. Just round the corner there was a great coffee shop called Lo Simple and a place called Confitería La Perla de Almagro to buy facturas for breakfast. We were travelling with an 8-year-old who loved the children's playground just half a block away. Las Violetas cafe/restaurant was a couple of blocks away, with amazing cakes and afternoon teas (Meriendas).
The house had everything we could want for our stay. The beds were comfortable, there was good heating and air conditioning, and a lovely patio with a washing machine and drying racks for our laundry. The two bathrooms and three bedrooms were perfect for us and the house felt spacious. Communications were brilliant, and we'd gladly stay here again!
