We stayed here for 5 weeks in the heart of San Telmo. It's a great location -- a block from The Market and Sunday street fair. There is a ton to see within 20-30 minutes of walking. It's also easy to grab the metro and see Palermo and some other neighborhoods, which we did a few times (we also had a car parked at the lot at the corner for about $50 USD for the month). We were surprised when we walked in at how huge the place is. The ceilings are probably 5M high. There is a lot of space. We enjoyed looking out over the city every day from the balcony. I was able to work on the wifi the entire time without issues -- very fast. It doesn't reach every part of the apartment, so pack an extender if you want to make sure you have wifi everywhere. The host is super friendly. The guidebook is great, but Grisel was always available to answer questions too. Of course, if you only like new, high-end stuff, this place isn't for you, but we would definitely stay again!
