We stayed in this great apartment for one month. The apartment itself was excellent; very neat, very clean, with all the facilities we could want (with one exception). The apartment is just outside the old town, but easy walking distance to all the old town has to offer. We enjoyed experiencing the Spanish lifestyle of the permanent residients of Salamanca, rather than the tourist experience of the center of the old city. The only difficulty we had was that there was no internet connection at the apartment. The Spanish phone system does not cater well with connection to the net via "hotspot" on our Iphone, which meant we spent some time at the phoneprovider's office. The apartment does not have airconditioning, but despite a very hot summer, we did not find this a major issue.
The lady who cares for/cleans the apartment kindly met us at the bus stop and took us to the apartment. She was very friendly, despite the fact we speak no Spanish, and she speaks no English.
We did not need a car for the whole period, we just rented one from time to time to visit the many interesting towns and national parks (and Portugal) nearby.
Highly recommended.
