I've spend a nice week in Sevilla. Host itself was amiable, kind and open to help with request that may pop up. The apartment itself it is quite good, clean and well equipped, having the possibility to cook without any issues (for those willing to do it in vacation). Being located in the historical city center it gives access to both touristic areas and common city as well. This is also a bit of disadvantage as access to public transportation requires a few minutes of walk. There are plenty of bars, terraces, restaurants and groceries shops in the neighborhood providing access to good food and drinks :).
It's definitely a good choice to be used for a few days stay in Sevilla. I would say ideal for a couple looking for a few days away.
