I would firstly say that it is in a very good part of town, its vibrant and fun with lots of brilliant restaurants and shops and quick access to several Metro stops.
The space is well heated and cosy for the winter months. It is smaller than it looks in the photos so I would not book for any more than two people. The main bed is in a loft which is nice and cosy and the ladder access is ok depending on how you feel about heights. The second bed is an uncomfortable sofa bed that takes up the whole common area so I'd really only recommend the place to a couple who can use the loft bed. The place is relatively clean but there was a dish of caked soap, some old sponges, almost empty food boxes and gone off milk in the fridge. I have suggested to the hosts that these are things to look out for in the future. There are also a few cockroaches in the bathroom but this is to be expected in any city apartment. They were small and we were unbothered by them. The apartment is under one of the main access stairways to the building so it can be loud at busy times and at the weekend, mainly in the bathroom. Check in is seamless and correspondence with Elisa was fine, she did assume myself and my friend were a couple and hadn't had the second bed made up but it was rectified quickly.
Im hoping the hosts will take our suggestions on board to make it a better experience for future guests. Based on this experience I would not book again but if they took onboard the very easy and inexpensive suggestions (replace sponges between guests, buy new handsoap, clean unnecessary food out of the apartment between guests, include a box of coffee pods with the Nespresso machine) it would definitely improve my opinion and encourage me to book again.
