We stayed at Carlo's place for 6 nights. Upon arrival we realised this was a hotel set up to operate as an AirBNB without the hotel facilities. We were given the wrong hotel room compared to the listing we paid for on check in but this was immediately rectified with no trouble. Otherwise the room was spacious, new and comfortable. We enjoyed the San Telmo area for our first time to BA with it being close to all the attractions and night life in San Telmo. Access to public transport is fairly convenient. We would recommend Carlos place if staying in San Telmo as it met all our requirements.
