Julio was very friendly, welcoming and quick in responding. The flat is cozy, full of amenities, very well located near Retiro, but in a quiet street with virtually no traffic. You have all kind of shops, malls, bars and restaurants in the nearby, a taxi stop, public transport, etc. It's big enough for a weekend with kids, and the owners left a ton of guides, maps, tips and books on local interests. Will book it again with no doubt!
