This was an amazing place to stay with an equally wonderful host. César was very communicative and accomadating, going above and beyond to help. For example; I was traveling with several very exhausted students and he graciously picked us up from the train station and showed us where to eat before completing the check-in. Four of us were staying at this place and so César made up an additional bedroom in the dining/living room for us. He left a very thorough handbook for the apartment and the area and provided a tranbía card. He was quick to respond to any questions before, during, and even after our stay.
The place was clean and comfortable with everything we needed to feel at home. Being a group of unrelated people, the 2 full bathrooms were essential. One the few nights we didn't have somewhere to go for dinner it was easy to cook and eat at home. Halfway through our stay César delivered fresh sheets and towels, so we felt very clean as well as comfortable. Between this and all the other things he did for us, we felt spoiled.
As for the area, one may be tempted to stay in the downtown when visiting Vitoria-Gasteiz but I was very pleased with the location. There are plenty of cafés just across the street and a market about a 5 minute walk away. Also 5 minutes away was the tram (which César explained to us) that quickly and easily gets you downtown. With this ease of transport I see no reason to overlook this place for a more "central" location. Additionally there are plenty and frequent buses, but I only used this service once, quite late when the tram stopped for the night. Because of the location we were able to easily access the Green Belt and other lovely areas to explore. We borrowed bikes (which César helped us store) and were delighted by how easy it was to bike anywhere we wanted to go.
In short, we were very satisfied with our stay, having easy access to downtown while getting to stay very comfortably, and, affordably.
