Guille's place is ideal for a city stay in beautiful Buenos Aires. It's in a very central location within walking distance to a lot of the sites including SanTelmo, Recoleta and Puerto Madero. It's also close to the ferry terminal if you're heading to Uruguay.
The apartment is spacious and well appointed. We stayed for 2 weeks and were very comfortable there. Guille was a great host, always available to answer questions and give us tips on getting around.
We found the bed to be a little lumpy, so we sometimes slept in the lounge. Guille was aware of this and is going to replace the mattress. The only other thing to mention is that city living can be noisy at times. We found that headphones adequately blocked out any noise from the street.
We highly recommend Guille's place, and would definitely stay there again.
