Found the apartment after getting off at Callao metro station (has an elevator for suitcases). Plaza photo helps but doesn't place you at the doorway. The entrance is down the side of the building and once inside, the apartment is on the 5th floor (actually on the 6th floor but has elevator too). Giselle met us at the suite and showed us the room exactly as the photos. She speaks good English and was very kind and helpful in all regards. Allowed us to cook & reheat simple meals too. Downtown location was perfect, as we walked everywhere. Saw Charles a few days later, he was nice, but kept to his room as we all did most of the time. Simple, clean and a good price. Found the bed comfortable (if you like a hard bed), but the room is small and has single table & chair, one of us had to sit on the end of the bed. No common sitting area available.
Bathroom was kept clean and always smelled fresh. Hot water was inconsistent so it made for quick showers. Wet yourself down, soap, and quick rinse before it got too hot or too cold was really the only way to do it.
If your looking for a great location, with a nice host, but don't have convictions on space, this is a good choice.
