I really liked Hotel Daval. The value for money is great. Bathrooms are tiny but functional. As a solo traveler I loved the location—it's an area where a lot of young people are out and about so it felt safe / busy. If you're a light sleeper, bring earplugs. It's walking distance from lots of sights and well-connected by metro stations. Overall very clean.
It wasn't a huge problem for me as I had lots of data on my phone, but the WiFi did not work for the entirety of my stay of 5 days. I brought it up to reception twice, but in one case, they said to just restart my phone (though I said I'd already done that) and in the other they offered to change my room, but that wouldn't have made a difference since my phone wasn't working in the lobby or anywhere else. They said this was not a problem for any of the other guests, so I do get that they didn't have many other options, and they were polite about it, but it's worth noting for people who are on business and/or need to rely on WiFi.
