Sandra's place is a great value! The apartment is small but very organized and it was recently renovated, so the kitchen and the bathroom looks modern. The bed was good and the apartment doesn't get too cold even on the coldest days, which was a great surprise in the winter! Just make sure you pay attention to the late check-in fee (you have to pay if you arrive late), as it can be quite high if you're staying just a few days.
Sadly the bedroom have a faint smell of humidity which can be a turn off for some people, specially if you have allergies.
Overall, our stay was very good and Sandra was a great host, she showed all the quirks and features of the apartment upon check in and was very responsive as well.
