We were told to "text or call" upon arrival so that've could be let in to the apartment - however, being international travelers with no working telephones (excluding wifi), this was not easy to coordinate.
The apartment is charming, and in a central location in the city. Our experience was positive, with a few notes for future guests: wifi signal is quite weak and only works near the front door. Check out is at 10am SHARP. The cleaning lady unlocked the door to the apartment at this time precisely. A later time might be difficult to negotiate (we tried).
Keep in mind that this apartment is managed by a vacation rental company and lacks the homey, personal charms and touches that we have enjoyed with so many other Airbnb accomodations.
