I had a nice stay at Christina and Paula's apartment.
It's a beautiful space with tall ceilings, lots of light, and it has everything one can need, down to the beach accessories.
It's 5-15 min walk to all historical sites, there are all kinds of stores and cafes nearby.
The only downside was it was noisy during work hours, but Christina and Paula did everything possible to make me comfortable.
Christina was a very welcoming and accommodating host throughout my stay, and would respond quickly whenever I needed something.
