We havent met Markus, instead Marina dealt with everything. She was a great host , she even brought toys and books for my 3.5 year old son, she greeted us when we were there and gave us all the necessary information and made some suggestions.
The booklet in the house that is prepared for the guests is very useful, we tried some restaurants from the list and they were very good.
The surrounding is very convenient, very close to Dolores park and some supermarkets for grocery shopping, due to jet lag we woke up and slept at odd hours and could not try more restaurants from the list, so having a full blown kitchen really helped.
Kitchen has everything you would need to cook from the cooking utencils to all kind of organic herbs.
The pictures reflect the reality, very nice house, very good taste in almost everything used in the house. Clean and hygienic in general.
Overall great experience, and I would recommend this house to everyone.
