Stayed here for 6 nights and didn't want to leave! The first thing we noticed was how clean it was, especially as it's in a dusty desert! The cleaning team do a fabulous job.
The hostel is a nice size, pretty peaceful (or maybe it was just quiet when we stayed), secure at night, and our private double was a good size. Pillows could be more plump and smooth but that's my only slight negative point.
You can use the showers up til 10pm and they're fab, great pressure and always had hot water. You're asked to limit it to 5 mins due to being in the desert which I had no issues with :)
There's a good-sized kitchen, only has a hob so no oven or microwave, but we ate out every night so it wasn't an issue. There are plenty of places and things to do in San Pedro, and this hostel is within 1 minute's walk of all the bars, shops and restaurants. Perfect!
I worried about there being no air con, but did some research and air con isn't standard in San Pedro as it cools at night, so we left our windows open and it was ideal.
I have to mention the WiFi, there is a strong signal all over the hostel, even in the rooms - some big city hotels we've stayed in haven't even got signal in the rooms! It really makes a difference when you're trying to research tours or your next travel move.
To us, it felt more like a hotel than a hostel, there is a Hotel Corvatsch and other hotels in the area but for the price and quality we would definitely stay at Corvatsch again - I highly recommend it!
