On the last day of our stay, I've asked my wife what did she like the most about the apartment and she replied that she absolutely loved everything about it :-) The apartment is very well equipped from the kitchen to the bathroom and the Martina, Tomas and Valeria are great hosts.
We were traveling with kids and Martina went totally beyond our expectations in terms of all the extra things and help which she was able to provide us with in order to make our stay as comfortable as possible.
A suggestion for other visitors, when visiting the apartment over the winter, make sure to bring a pair of slippers as the floor is cold. But I guess that it applies to all the apartments in winter or might be just because we are bit more sensitive to cold :-) However Martina prepared extra heaters for us, and we also appreciated the carpets in the rooms.
In conclusion, the apartment is great, and the hosts are even better. We totally recommend!
