We really enjoyed our stay here and can definitely recommend it to other fellow travelers.
The apartment has a mostly quiet central location in the old part of Monterosso and is just next to the fantastic Wonderland Bakery and many other good restaurants. The apartment has a shower and small balcony (no sea view but the sea is super close by). (Almost) all the things we needed were provided on site: some cutlery, cooking utensils, a gas stove and oven and basics likeolive oil, salt and sugar were already in the apartment, as well as shampoo, towels, soap, disinfectant, hair dryer, towels, detergent, cleanser etc. The bed was comfortable and we had lots of pillows and blankets. There is a couch, a small TV (which we didn't use) and the WIFI is decent enough to stream movies and upload holiday pictures to the cloud. We had an air conditioning unit which we barely used, but when we did it worked well.
The water in the shower started to run cold after a few days (before we had hot and cold water). There was a power outage at some point which might have tripped a circuit or something and caused this issue, but we didn't mind the cold water as it felt rather refreshing. What we did miss more was enough space to dry our clothes. Initially we only had one pole line. Our apartment contact responded withing hours and fixed the missing pole lines the next da. He was very friendly and super trustworthy! But even after that drying space was still rather limited.
