We stayed in Marta and Paul's place, two couples for 4 nights. The apartment is beautiful, new, very clean and well decorated. It was very convenient for us all and location is unbeatable.
Paul is very nice, very available and responsive.
However, a few issues should be noted:
The wifi was slow and we experienced a lot of disconnections, the boiler was not sufficient for four persons, and we ran out of hot water sometimes. The owners do not provide basic things such as sugar, coffee, shampoo, body soap and more - you will need to buy a lot of things or bring from home.
Please not- there is a check in fee (50euros) and another tourist fee you would need to pay upon arrival.
Overall experience was very good, and we would recommend staying in this beautiful apartment.
