I stayed at Adrians place with my (adult) daughter , our first trip to Valencia. The location is perfect, right in the centre of the old town. Arrival and check in was very smooth, as was communication. Very clean, and well equipped apartment.
One of the main reasons we booked was use of the Jacuzzi, to relax in after a day of sightseeing. From reading the reviews, we expected to spend a few euros on the jacuzzi electricity, as this is metered separately. The meter only takes 1euro coins, and its pretty hard to find so many 1 euro coins. The instructions for the jacuzzi could do with more detail, - no mention of the tap on the waste pipe at low level (which acts as the plug). Jacuzzi takes forever to fill, and even longer to heat, - allow several hours ! It would be easier if the meter took debit / credit cards. Also, ( only a minor problem) there is a slight smell of stagnant water from under the jacuizzi, Maybe its not used often ? Apart from that , Adrians place is top notch !!
