Let me start off with the location. It's a good hour away by public transport and about 35-40 minutes by car from the main tourist spots such as the city centre, Schronbonn palace, etc. However, the bus stop is less than 100 metres from the property so it's very convenient and the bus frequency is great.
If the travel to and fro doesn't bother you this is the place to stay. It's a very spacious and private room, more than double the size of a standard hotel room. Your own WC & bathroom provided as well. Comfortable bed and all the basic necessities provided to you.
Coming to the host, she's a really gracious and welcoming woman. She'll give you detailed information about any doubt or query you have and is an absolute delight to talk to. She also let us use her washing machine and offered breakfast to us on both the days when neither of those things were included.
I can conclude by saying if you want to feel at home in a foreign city and some travel to and fro doesn't bother you, this is the place to stay.
