We stayed in Carlo's apartment for 1 week. The place is as described, and we had a fantastic time. The apartment is located on the tram line with quick access into Valencia or to the beach. When in the apartment you can hear and feel the trams, but this did not give us a problem and they stop at midnight.
There are plenty of local shops nearby and a supermarket across the road. The apartment is well equipped and we were able to cook. The apartment is located close to a Pool and Water Park Benicalap - well worth a visit on a hot day and very reasonably priced.
Previous reviews commented that they did not feel safe in the area. However, this was not our experience. The area is diverse and there is a lot of graffiti but we always felt safe and had no problems.
The air conditioning is located in the living room. However, this was powerful enough to cool the whole apartment.
Lastly, Carlo was a great host and very responsive to our messages and checked in with is to ensure everything was OK. We would definitely recommend staying in Carlo's place - it's fantastic value!
