We stayed a month. Juan's place is almost ideal -- it's got a fine bed, good bathroom, a working kitchen (no stove though), etc. The wifi works great. The gym on the 27th floor is gorgeous and we spent quality time hanging out at the pool outside downstairs. Three drawbacks: 1) Chromecast wouldn't work on the television, 2) the noise from the street below is fairly loud, so you can't really sit on the balcony, 3) there is no desk or office chair, so not ideal for working. Nonetheless, I really enjoyed it, and the location near San Telmo is terrific. Would recommend!
