The good
Location is perfect (Plaza de la Merced). You can't stay in a more central place with access to countless bars and restaurants. The old town of Málaga is just a minute away from the apartment and the patio is just awesome. Apartment is clean and looks as described on the pictures. Check-in was super easy and flexible and Lidia (host) was very helpful.
The bad
What you should check with the host is, if the sun bed got fixed. During our stay one sun bed was broken and unusable. Also the Wi-Fi in the apartment does hardly work. You can connect to the Wi-Fi, but that's about it. Download rates are about 0,9 Mbit/s. Since several visitors pointed that out before, I think it's time to get this fixed. For your visit, make sure you have a data plan for your mobile or get in touch with the host in advance.
Verdict
If you don't need Wi-Fi and the sun bed gets fixed, you can have a wonderful time in this apartment. Despite the nuisance mentioned above, I would recommend this apartment. The patio and the location of the apartment is just too good.
