Can thoroughly recommend this apartment. It is an apartment with real character (sleeping in a dome!!!), attention to detail and centrally located close to all amenities and the public transport network.
From our very late check in right through to departure Nicolás was the perfect host - on hand to answer any queries and quick to give useful tips and advice for us on our first visit to Buenos Aires.
I thought I had accidentally thrown an expensive pair of headphones in the bin and messaged Nicolás to ask if I had left them behind. The bins where even searched for the headphones (which turned up at the bottom of my suitcase)!
In short - a perfect apartment with the perfect host and would happily recommend this apartment to future BA visitors.
