Nice little studio apartment located about 7-10 minutes walking from Centro.
Check in was great and Ramiro was very friendly and communicative.
Nice comfy bed, AC works very well, and wifi was also superb. And it was certainly nice and clean.
The patio is also a great little spot to hang out in the morning and read a book and drink coffee.
The kitchen is not overly loaded with equipment, so bear that in mind if you're looking to do a lot of cooking for yourself - it may not have all of the things you need. It does have a frying pan and a pot though, so for the most basic things you can get by.
For a solo traveler or couple who are passing through Malaga for a night or two, this place will likely fit your requirements!
