Spent a week in Veronica's apartment. Excellent location, excellent building, super clean, and spot on attentions.
We did not meet Veronica in person, but she was quick to respond any question via chat.
The flat has all the necessary amenities and a strong internet connection.
Because of the location, there can be times of the day that it might be noisy, but thats something you'll get anywhere in Centro Histórico. The apartment is serene and quiet at night.
Would highly recommend for short stays in town.
