All aspects of the location such as its relatively close vicinity to the city center, a quite neighbourhood, access to the public transport, to name but a few, make Paul's place a good choice.
Apart from the nice location settings, the host is a wonderful person who was available for any questions from the moment of reservation. Upon arrival Paul was kind to pick me up late evening at the tram stop. Furthermore, the host was very helpful in getting to know the area better, and US/European politics too.
