Daniel and Silvia were great hosts, keeping contact with me and helping with my queries.
The apartment is amazing! It is on a busy road which is great for catching taxis and buses but, because the apartment is at the back of the building, it is also very quiet. The added advantage of this is the fantastic view of the skyline, and I enjoyed many sunrises and sunsets from the apartment. There are some really good shops about 7-10 minutes away, with an Organic food market, patisserie, supermarket, laundry all nearby. The Subte is a 10 minute walk and very easy to get to.
If you dance tango, the apartment is located near some very popular milongas...Club Fulgor, Villa Malcolm, La Viruta, Salon Canning, La Bicicletta.
I would definitely stay at the apartment again. It's a great place in a great location, with fantastic views :-)
