Great flat - modern, open space concept with all you need as a traveler. Probably only fit for two people due to the overall square footage, but has all you need. It is a bit noisy with people walking above you or dogs barking in the ally. However this apartment does not face the main road so you can't complain too much...after all it is a busy city! Martin was an amazing host. Very kind and readily available before and during your stay. Would recommend working with him on any of the spaces they have in Buenos Aires!
Cheers and happy travels!
