The appartment is perfectly located for Buenos Aires because it's located close to everything. You can walk to recoleta or Alto Plaermo or take a taxi to plaermo hollywood, Belgrano o San Telmo from there and it will take only minutes (aside from peak hours).
The appartment is spacious and comfortable, except for the bathroom which needs to be renovated (apr-12).
What is good about this apartment and needs to weightes is Cameron. He's a great host. I requested him to add a password for the wifi and he did it. When I needed extra power plugs for laptop and charging mobile phones he provided it on the following day. Always very helpful with my family and no problems at all with check in and check out. This is not easy to find in Bs As, so I will recommend this apartment and rent it again on my next trip to Bs As.
