(+) pluses
the flat has an excellent location, clean and looks very good and more spacious than it is in photos. nice supermarket with all-you-need just across the street.
(-) minuses
only one person could connect to the internet for work, the other one had to go to co-working or use mobile data. modem/ router was in a different flat and network was unstable with too many users connected. the flat is rather noisy, it is located on the first floor with windows facing the road, so during the day you hear buses outside and in the evening - neighbors. we were lucky that the group of people staying behind the wall were understanding and reduced the noise in the late hours after I approached them.
in general, the flat is a better fit for a weekend stay while exploring the city and not really suitable for "home office" and longer stays. Sergio and Elena were communicating fast and trying to help.
