This was truly a great place to stay! Rocío & Nicolas were fantastic hosts, even though we never got to meet, mainly due to us being so busy trying to fit as much in as possible. They were always quick to respond to any questions we had. We are usually quite self sufficient travellers but their recommendations were great considering Buenos Aires is such a large city! Also leading up to our arrival they were really helpful in providing useful info including getting to the apartment among other things.
The apartment is great with everything you could need and was very clean on arrival. The location is also awesome with supermarkets, farmacias, restaurants and bars all within a couple of blocks, if not the actual block itself. There is no laundry but there is a laundromat about 4 doors down so no problems there (not open on Sunday).
Most parts of the city are walkable from here (down town is a 1 hour walk, maybe a tad more), but if walking isn't your thing there are buses at the front door and across the road, literally. There is also a metro stop about 4 blocks away and is super easy to navigate.
Not sure what more I can say about this place it was awesome and I would definitely stay there again if I make it back to wonderful Buenos Aires!
