Everything what is described is true: it's a small and old apartment. HOWEVER: The strongest points are:
Really convenient bus transportation (bus 1 or 2)
Carolina and Vicky are really helpful and they will ask you in advance what do you need, and then they will answer with a lot of detail what you need to know about your requests.
At your arrival we were lucky and we received appetizers (which are really nice if you're coming from far away and you haven't eaten cause you're trying to arrive on time)
The arrival hours were really flexible (Thanks Caro and Vicky!!!) and they are not complaining at all if you couldn't make it as agreed.
WiFi speed is great.
We were lucky and were offered fresh orange juice in the mornings and some cake/fruit.
Vicky's attention is awesome.
Thanks once again!
