Andrea is a gracious host and gave us many local recommendations.
Her lovely spacious apartment is literally in the heart of San Telmo: the Sunday markets are around the corner, Plaza Dorrego is a short walk, and there's plenty of bars and restaurants in the area. The kitchen facilities are great if you want to cook, and for groceries there's a Carrefour supermarket on the adjacent street. The double room was comfortable and clean, overall we had a great stay at Andrea's.
