We had a great time in Serge and Paul's appartment. It's a nice and cozy space, which had everything we needed for our stay. The kitchen was well equipped so we could cook our own meals. Paul was very welcoming and we could even check-in a little early. We were also strongly encouraged to use all the "extras" of the appartment like air conditioning and the washing mashine.
The flat has good access to public transportation and we got a 72 hour ticket for tram & bus for sightseeing.
We can only recommend the flat :)
P.S. Bonus points for having fresh basil which we could use when cooking, lovely!
