The flat is very clean, with a good bathroom and shower. It's light. The kitchen is spacious but not well equipped for actual cooking e.g. no oven only microwave and few utensils. When you check out, you can leave your luggage in a left luggage cupboard downstairs if you arrange beforehand, which is very useful. But note you may be sharing that with others, so it's not private. Wi fi great. Small balcony at the back.
It's a long way from the centre- a half hour walk. That makes quite a difference if you've spent the whole day on your feet already, or if you want to pop back in the day. The area it's in is OK but not particularly interesting- OK cafes and small fruit and veg shops and gelato shop but nothing you'd go out of your way to visit. Supermarket v near on opposite side of road. It's on a main road ( you don't hear the traffic). The building seems to have a number of other tourist rentals.
We were there right at beginning of June. Even then, using the sofabed in the lounge was almost impossible because of the heat and lack of air (the fan didn't work- it was broken). There's no air conditioning and I think the flat would be uncomfortable in the summer. We were just on the cusp of that. Woken at 8am by workmen drilling loudly (stopped at the weekend). Walls thin and you can hear next door and above. Very utilitarian inside-just the basics.
Host replied quickly at the beginning before we arrived and was helpful. It's run by a business. But then once we were there, didn't reply promptly at all, which was a bit unnerving, if there'd been an emergency. Had to chase for reply.
