The pictures and description are very accurate. The location is in the centre of historic part of Valencia and we walked to all the main historical sites and to the new science park. We walked to the beach but it took an hour so we took transport back - which just takes 10 mins or so.
We had everything we needed in the apartment for a short stay and Susana made everything very easy for check and out.
Wifi worked well as did the aircon - so we were glad to come back to a cool apartment with nearly 40C outside.
The central market opposite is great and we enjoyed walking around Valencia.
The stairs are mentioned in the description but I would say that anyone with trouble with stairs would not enjoy getting up them but we were fine.
Due to the location in the bustling centre of Valencia we did get quite a lot of street noise up to 3am but that's often the same in many places.
All in all a great place for a city and beach break in Valencia.
