Carolina is a lovely host and very responsive. Although we have not met her in person, she solved all our problems, such as no hot water on the first morning, on the phone and via WhatsApp. She even offered to lend us hats for Royal Ascot!
The bathroom smells quite strongly of rotten water, even in summer - may be worth turning on the heat.
The upstairs neighbours are quite busy and move around from early morning to late evening - better bring earplugs.
