I too have used them to sell a small townhouse my family owned in Valencia. They are very professional, easy to deal with and frankly, couldn’t be more helpful. For less than €300 you cannot grumble (their advertising cost may have gone up).
Personally, I think it is high time the ridiculous fees of traditional agents were stopped – in the modern age, buying and selling houses through the Internet is a fast, efficient and easy way to do business.
Alongside sites such as this, things really have moved on in Spain and there is no better way to avoid paying the arrogant estate agent than selling yourself privately for a fraction of the cost!
