If you want to find a cozy place, with a reasonable price, we suggest using the Airbnb concept.
Through this website you can rent either an apartment or just a room; for days, weeks or months! There are many offers and options, depending on what you are looking for. One of the advantages that we really appreciate of this systems, is being able to share with a “local person” who knows the surroundings and can provide you with some interesting “tips” of the city.
Usually the Airbnb service is a little bit cheaper than hotels.
