Melania is a great host. The communication with her is really easy, she gave us great tips and recommendations for what to do during our stay and she is generally kind and helpful.
The apartment's location is perfect, especially for tourists. Every attraction is at maximum 20 - 30 minutes of walking. The center is full of great places to drink and eat. We felt pretty safe, too. There was a more dubious street in the neighbourhood, but it wasn't very close by and you can avoid it (it is to be expected, as the center of any city is big and full of surprises).
The apartament is exactly as in the photos and description. It has everything you need. It is small, but we knew that from other reviews. However, it is comfortable, it has AC for the hot days, and it's perfect for when you just need a place to rest after a long day of walking.
I recommend this place to everyone that wants to experiment the full pulse of the city and doesn't mind that the place is a little small.
