Our party consisted of 2 familes of 4 people each plus 2 single individuals (10 total), and Casa Nirvana had more than enough space to accomodate us comfortably. The house is fantastic and the outside pool area is exceptional and we basically spent the vast majority of our time outside around the pool, in the pool or under the fantastic gazebo type structure which has an Alexa, fridge, fan and basically perfect for spending an entire day under it. There is also a nice tree and 2 parasols for additional shade during the day. The pool seemed very easy to keep clean and cleaners came once a week so there were no problems at all there and the pool is both large and deep, it would be difficult to imagine a better pool for a private house.
We "only" give 4 stars for facilities because of a couple of really quite minor niggles (and 4 is still a very good score). There is a shutter in front of the studio patio doors that kept getting stuck and wouldn't raise fully. This wasn't a huge deal because we didn't want the sun blazing in there all day anyway and it always raised enough to let in plenty of light. The same shutter was obviously invaluable at night for keeping light and noise out. The facility manager also seemed concerned about the septic tank, and strongly emphasized us not abusing what we put in the toilet (which we observed), so there was just a minor concern at the back of our minds during our stay but aside from a couple of gurgles from a toilet it had no impact. The rest of the facilities are all described and shown well. There is a good tv with a couple of Alexa's, and the internet connection seemed really solid. There are two large fridges in the house plus a smaller one outside, and even another one in the studio (which could be fully self-contained). It also should be mentioned that the air-con worked perfectly which is important these days.
We also deduct 1 point from check-out because we feel 10am is just a little early, especially in a house which will often have such a large party. The process itself was very painless and it must be said they were very good at accomodating our late arrival on the first night. And also Raima's english is really good.
The only other thing we didn't give 5 stars is the area, but really it could have been 5 stars. I guess in a perfect world you could walk to several shops and restaurants, or a beach, but there is a good local shop about 15 minutes walk away, several larger supermarkets within 10 mins drive and several really good restaurants within 10 minutes drive also. The house is right in front of a spectacular mountain which dominates the skyline behind the property (in a very positive way, no interferring with the sun at all) and the view of the front is into a valley and is really nice, especially in the mornings. There are 2 very busy coastal towns/beachfronts around 10 mins drive away each (Xabia and Denia). For anyone wanting to go further/bigger, Benidorm, Alicanta and Valencia are all within 60-90 mins drive.
Overall we rate the property 5/5 and would unquestionably recommend it. If we were more frequent holiday makers who didn't want to see other places, we would definitely go back and we enjoyed every day of our 2 weeks there.
