My friend and I stayed in Carlo's apartment for one month and on the day of arrival Carlo allowed me to check-in early which was really great. He is very welcoming and gave me a map and lots of great information about things to do while in Valencia.
Even after that Carlo kept in touch with me during our stay to make sure we were okay and he is a great host and a very nice man.
As for the apartment it is located an area with lots of supermarkets nearby (Consum, Mercadona, Lidl) and there is a great gym just around the corner that I joined for the month.
The internet is very good and the kitchen has a good gas cooker with an oven so it was easy to cook whatever we wanted in the apartment.
It's about a 30 minute walk from the city centre and 10 minutes from the metro station. But there is a tram stop very close by and I would recommend you use this to get in and out of the centre.
The tram will drop you off about 5 minutes from the start of the cafes and restaurants and the beginning of the tourist areas. As the tram is so close and the line is right outside there is a bit of noise when it passes by but we got used to during our stay.
Overall a nice apartment in lovely Spain and a great host in Carlo. Thanks again for everything and all the best! :)
