Tomás' apartment is big, bright and airy with a huge comfortable bed and a TV area for chilling out and brushing up on your Spanish by watching Spanish TV (which we did when we were worn out from exploring!). Although near a main road, you can't hear any traffic noise in the apartment - it's soundproof!
Tomás kindly let us check in really early on a Sunday morning after our overnight bus from Mendoza which was greatly appreciated. He'd left us a bottle of water and some milk which was great as I could have my morning cup of tea!
Tomás was really quick to respond to any of my message and queries and gave us loads of tips of things to do/places to visit. The area felt very safe and there were plenty of cafes, shops, grocery stores around plus the Subte on your doorstep. We walked everywhere around Palermo and Recoleta with no problem.
I highly recommend staying at Tomás' place if you're in Buenos Aires and I would love to return one day!
