Steep climb, indeed. It is not the same as the much feared one before Orisson, but I had to stop to catch my breadth some moments.
Good thing, you can get rid of this same section when you walk to Roncesvalles.
This Villa seems nice. I am actually a bit envious...
It really is up to you, and your habits (mainly, if you are the type of tourists that come back frequently to the hotel, or spend all day visiting)
I mostly be worried about what to do in Saint Jean in two days. It is a little village, you can walk the historic part in five minutes.
Tips: *Pilgrims' Blessing in Notre Dame;
* a gentle stroll along the Nive (the same pictured in "The Way", when the character cant' figure out where is the road to Roncesvalles);
* the Citadel fortress;
* take a taxi to Saint Jean le Vieux, and follow the pilgrims walking to SJPP (they are coming from Arles or Le Puy....you will see how you will look after many weeks)
A couple of good restaurants, also, less expensive than those in SJPP. It is a pleasant one hour walk, clearly signposted.
* Thursday, there is a peasant market, where you can taste
real ham and cheese, not the pre-packaped thing available in supermarkets. And local wine, obviously.
* There is a tourist bureau (a kiosk) in the main avenue that divides the old from modern parts of the city.
Buen camino!
