Plusses - apartment larger than expected (about 6M wide x 7M), perfect postion for access to old town and with a sea view which is more interesting than the internet photo indicates (dragon tree, old building, rocks and waves), settees (3 seater and 2 seater) both very comfortable), good Wi-Fi (not mentioned in the description as at Feb 2016), no problem with noise from adjacent apartments or from the street at night (which we'd feared) though the waves are obvious (and, to us, relaxing)
Minusses - The "Bathroom" which contains a shower, WC and basin is small, the TV has no english (or german) language channels, though there is a DVD player so you could play your own DVDs.
Other thoughts - Smoking in restaurqants is not at all unusual - we'd forgotten how it used to be in the UK. Local buses are great - for example over the mountians to Los Gigantes (where dolphin viewing trip on Katrina - a 1940s shrimper - was good), also La Oratava (where we'd recommend Lercaro restaurant 30M down from Casa Balcones)
Peurto De la Cruz and North Tenerife is a happy place at peace with itself
