I had a comfortable 3 nite stay at Peggy's unit. The unit itself is spacious, with a large modern bathroom. The bed is also very soft and comfortable.
The unit is an easy 5-10 minute walk to the Grand and Lakeshore avenue shopping districts, which contain a plethora of shopping and dining options (including a Trader Joe's) as well as many bakeries, cafes, and banks. The lovely Lake Merrit and Grand Avenue restaurants are also just minutes away by foot. Local East Bay public transit and Trans-Bay bus service to San Francisco is close at hand. The neighborhood itself is very residential and one of the best areas of Oakland.
The only issues for me were I was under the impression (from the description) that the unit was a completely separate "in-law" type accommodation whereas in fact it's part of a multi-unit building, with an unsecured door to the adjoining interior areas (hallway?). There is also some foot and conversation noise from the other building occupants (including a cat meowing and running about).
Travelers should be aware that there is no heating control in the unit (there is central heating) but no control of the settings. There is also no in-room A/V equipment. Finally, there is also a short but rather steep and uneven flight of stairs to climb in order to reach the unit. This might be a challenge for some mobility impaired people and should be mentioned in the description.
Overall, I was happy with my stay and Peggy was a very communicative, if unseen, host.
