Great place, location and communication. Bernard was available in minutes the few times we had questions via ABB chat. You can walk to all the sites within 15-20 minutes. The internet is very fast.
The trams are right there and we also used the city shared bike system. It is at the junction of two busy pedestrian streets with bars on them but you hear nothing at all in the in the back bedroom and little in the front - more than manageable. Only issue was we used the local carrefour by the Sherlock Holmes pub and were not impressed by the selection nor quality so we would advise trying another supermarket.
We stayed for about 10 nights and took the train to the beach at Arcachon and again to St Emilion which made for a complete stress free days. The trams are very cheap and the B (walk towards the river across Gambetta square) to the C or D will get you anywhere in 15-25 minutes.
In St Emilion we would recommend to anyone Les Bicyclettes de Saint-Émilion -the young owner Marius will pick you up and drop you off at the station and you have different routes through the vineyards guided through by their goo gle maps. They really have nailed the experience. You will see far more than any tour at a fraction of the cost plus get a days exercise to wear off the effects wine and the French food. It really is fun.
In the evening you can sit in the Gambetta square and watch the work go by or 10 walk minutes up the road to the Jardin Public. Bernard's place is the ideal base to enjoy the your visit.
