Greg is a friendly and great host. Our family of five including three young boys had a wonderful three-week stay at his house that was located in a safe and tranquil neighborhood. His place was spacious, clean, comfortable and with a nice little garden for young children to play in. Greg was also so kind to have prepared a rice cooker for us beforehand, provided us with cereal, muffins and coffee to start us off for breakfast and was quick to respond whenever we needed his help. We highly recommend Greg and his place and it is a perfect cozy home for families with kids. If we do visit SF sometime again we definitely hope to stay at Greg's place again.
