Had a lovely stay here with my family. Helen and Martin were really responsive and easy to communicate with. Check-in process was easy - Helen and Martin were out of town so we met with Carmina (cleaner) instead, who was very helpful. The apartment is well furnished and very conveniently located, which made it easy to explore the city and visit the key sites.
A couple FYIs for future guests - (1) the apartment was pretty cozy for 3 people, (2) like Helen and Martin mention in the listing, there's a limited amount of hot water available at a time. You might be able to take 2 hot showers if you're very very quick, but otherwise should plan to spread them out.
