Had a great time in Valencia staying here with our 2 kids (3 & 7). Location is excellent right round the corner from the cathedral and very close to the Turia park (for those with young kids there's a play park there 5 minutes walk away next to Pont dels Serrans), loads of restaurants and cafes nearby. Apartment was great for us, all the amenities you need. Kitchen also had some basics (salt,pepper, oil, tea bags etc) which was really useful. Pilar was very responsive to messages and let us drop our bags off early instead of having to wait until 4 to check in.
Only slight negative is we were woken a couple of times in the night during our stay with people heading back to the youth hostel at the end of the lane. Not a big deal and I guess anywhere in the centre of the city will have some street noise.
Overall we had a great holiday and would definitely stay there again.
