My wife and I had a great week and a half at Eduardo's place. Eduardo was one of the best hosts I've had. A lot of Airbnb's have turned "commercial", which takes away from what Airbnb is supposed to be - people renting from people. Eduardo was friendly, flexible, and easy to work with. Many other Airbnb's now have big companies managing them, which leads to a lot of strict policies, rules, and threats. Eduardo met us when we arrived, helped us get to know the place, was available whenever we had a question, and also helped us with our luggage pre and post-check in.
The unit is in a good location and close to the Obelisk, Teatro Colon, and Florida Street (good shopping). There was also a gym close by that we purchased a 2 week pass to for very cheap. The unit feels like a cozy home with a lot of character, such as books and artwork. It also doesn't face a street, so it's very quiet. Everything we needed was there- cookware, full size fridge, a washing machine with soap, etc. Wi-Fi was fast (clocked it at 135mbs), and A/C units worked great. Only negatives is the bed is quite firm (although some people might like that), and no way to connect/stream your services to the tv. Overall, one of the best bangs for your buck in BA!
