Martina is a great host. She provided excellent directions for getting to the flat from the airport, which is very straightforward, and had lots of local knowledge to share regarding where to eat/drink, interesting attractions to see and what to avoid.
The flat itself is lovely, every bit as homely as Martina's description suggests. It's in an excellent location to, within walking distance of the entire city centre and also near plenty of public transport links if you're wanting to explore further afield.
All in all, an excellent experience; a welcoming and helpful host, and a great apartment.
