I stayed at Adrien's for four nights in December. Unlike some places I've stayed at before, this place felt very much like a home and I was very comfortable there as a result. Nicely furnished, peaceful, even when I was playing the piano, maybe... A definite plus.
The apartment is located at most two minutes walk from the Croix-Rousse metro station and directly onto the local market when it is being held on the boulevard. There was no problem at all finding it from the directions and Adrien was waiting for me in the apartment on arrival. You've a small seafood shop to your right (also sells wine and you can enjoy both on the premises), a bakery next to that. Interesting antiques shop to your left. All rather perfect.
The wider Croix-Rousse area was nice. It felt a bit more alternative compared to some other parts of town. I'd take the stairs down the hill past a pirate garden and hilarious anarchist posters. Again, the sort of thing that made me feel at home.
Yes, the hill... It is worth bearing in mind that Croix-Rousse is at the top of one. You can let the metro do the hard work or walk your way up. There are some nice small bars nestling away for both the ascent and descent. You also get a fine view down into the city.
Although I've visited France many, many times, it was my first real visit to Lyon. I thought it was pretty great. I ate, drank, walked, looked at architecture, visited absolutely no museums (they do have them!), bought old books and records. These are things I do in many cities and Lyon was an excellent place for all of these. I'll certainly come back and I'd certainly love to stay here at Adrien's again.
