We enjoyed our stay in Kari's apartment, although we were disappointed that the home wifi was not working during our five-night stay. It made it difficult to research what to do in Valencia and make restaurant reservations. We had to use wifi in cafes around Valencia (luckily the lovely cafe across the street from the apartment had free wifi).
The apartment was clean, comfortable and just as expected from the photos. Kari provided some essentials like towels, shampoo and shower gel. There wasn't any toothpaste which would be a good essential to include for future guests. There was plenty of storage space and a well-equipped kitchen. As it is on the fourth floor (no lift/elevator), it was very warm at night but Kari provided a fan and there's air-conditioning in the living room. The apartment is very well-connected to the city centre & city beach by various bus routes. It is 10 minutes on foot from a metro station. If I came to Valencia again, I would probably stay closer to the city centre because we spent a lot of time travelling in and out of the centre and waiting around for buses.
