Harald's place was wonderful. The location was great to explore all areas of Valencia. There were tons of restaurants, coffee shops and shopping within walking distance. The metro was about a 15 minute or so walk and the bus about 10 minutes or so. The apartment has an elevator and a host was there to greet us at check in. Communication with the owner was almost immediate and very professional. The place is huge and nicely decorated. It was like a small hotel in itself. The bathrooms were both very nice. We were also left a bottle of wine which was a nice welcome gift.
The place was very clean and Harald has a wonderful house manual outlining all areas of Valencia including food recommendations. Our favorite restaurant within 5 minutes walking distance was Musasa. We ate there three times.
The apartment was very clean. It has a washer and a clothes line outside. Be aware that hardly anyone in Spain has a dryer if you want to wash clothes so plan extra days in to dry your clothes. There is a separate tv room. You can sign into your Netflix account on it. Bring plug converters - they have new ones that have a usb port so you do not need a block. We also really enjoyed the terrace for unwinding. Shampoo and body wash were provided but you need to bring your own conditioner which was the norm in Spain.

The apartment felt very safe. We also liked Blackbird coffee around the corner. This city takes its siesta very seriously so plan ahead. And restaurants have different hours on different days so you just have to be flexible.
This is definitely one of the best air bnbs in which we have ever stayed and the host was superb. Do not hesitate to book it.
