First of all, I would like to list undeniable advantages of my stay.
The apartment location is marvellous and is probably one of the greatest that you can think of in Seville! Close to the old part of the city but at the same time with great access to modern part and main roads and bike lanes. At the same time the street itself is narrow and quiet without many tourists. If you like walking or cycling you can get almost anywhere in the city within a short period of time without using the public transport.
Elena is a very kind and hospitable host. She stays in contact with her guests and reacts to any potential problems and concerns immediately. At the beginning of our stay she gave us a great advice of buying second-hand bikes in the local shop for our stay. We are very satisfied with this advice!
The apartment is equipped with new modern appliances e.g. new Junkers water heater and new washing machine. Other kitchen appliances are in a very good shape as well (dishwasher, fridge and fantastic toaster). Moreover, the apartment décor is really nice. It feels more like home than a hotel room. There are a lot of books and CDs which can be used by guests during their stay.
One of the great advantages of the apartment for people working remotely is perfectly stable internet connection (fibre to home technology) with easy to access router for cable and wireless connection of your devices (LAN cables not included in the apartment). It is very stable and reliable. We did not lose connection single time throughout our long three-month stay. Furthermore, there is a small (but sufficient) Samsung FullHD TV which can be used as additional monitor to your laptop (bring a HDMI cable with you).
The apartment has an access to a shared rooftop where you can dry your laundry or chill out with a drink. The patio outside is nice and secure as it has a CCTV camera watching bike stands 24h/7. The neighbours are nice and there were no incidents during our stay.
Unfortunately, there are also a couple of disadvantages which must be mentioned.
The bathroom is well equipped and everything is working, however, due to its location and lack of window it is very difficult to air it. We have been using the bathroom with the door open all the time. Moreover, the ventilation in the bathroom is mostly useless. It works but its power is so weak that it does not help much with air circulation. Due to all of the above, the fungus is growing on the shower ceiling. Despite keeping the bathroom door open all the time and using the ventilation, there is an odour coming from it (especially at night).
Another disadvantage of the apartment is the acoustics. You can hear almost everything your neighbours are doing in their bathrooms.
Last minor remarks consider the limited equipment (cutlery, pots etc.) in the kitchen, but it rather applies to the longer stays.
Summarizing, if the bathrooms gets renovation, this is a perfect apartment for holidays (1 to 2 weeks). For longer stays (more than a month) when you plan to use kitchen more often it is OK but might depend on your requirements. Overall, we are satisfied with our stay. It was a three month stay for working purposes.
