We have nothing bad to say, the location was perfect and near everything you could ask for- the markets, shops, some great restaurants (we especially liked an asion restauraunt called Manolita Chen), and best of all, the Retiro park. The flat was very clean and prettier in person than the pictures, also equipped with everything you may need. Carine was absent during our stay but she was still very responisive and helpful through messages, and her mum who lives upstairs showed us everything. Would absolutely recommend to anyone who visits this beautiful city!
