I enjoyed my three nights at the Hotel Colón Rambla. I found the staff to be always friendly, polite and helpful. My room was comfortable, although the WiFi was forever dropping out.
I didn’t have breakfast at the hotel, so can’t comment on that, but I used the pool a couple of times (it’s good) and was surprised that they offered a drinks service there.
The hotel isn’t in the centre I guess, but it’s ideally located for driving in and out, and it’s only a ten minute walk to the shops, bars and restaurants.
The car park was full during my stay (I didn’t realise you had to book), but it is very small and not easy to manoeuvre in, so I was kind of happy to park elsewhere. Parking isn’t easy in Santa Cruz but you always find a place eventually!
